  • A quarry is operated for filling-up the New Busan Harbor which is under construction, but actual rock quality is something different from the primary design. Therefore, object of this study is to classify whole rock quality for the quarry through site investigation and laboratory analyses because unexpected large amount of wasted rock is produced. For this object, various analyses were performed such as surveying, Schimidt Hammer test. joint spacing investigation and laboratory analyses using DIPS & RockWorks programs for evaluating joint sets and sizes of rock fragments after blasting. As a result, it is expected that large amount of wasted rock under ${\Phi}100mm$ is produced after blasting because of high joint density.

  • The development of unsteady, depth-averaged two dimensional sediment transport prediction model in estuaries and harbors by the Galerkin finite element technique is presented. The model consists of two submodels, flow induced circulation model and sediment transport model. The sediment transport submodel is formulated by incorporating sediment continuity equation and sediment diffusion equation. Numerical experiments of the model, which were carried out in one dimensional channel under different conditions for circulation and sediment transport, show the adaptability of the formulation for predicting the migration of both cohesive and noncohesive sediments. The model was applied to Busan harbor to simulate circulation and sediment transport for simplified conditions. Of the results by the model the flow pattern are shown to be similar to observed data.

  • The port space can be considered to be the space in which the characteristics of the port city are best expressed. Also, since it acts as a representative gateway along with the airport, it can have a direct impact on the image of the region and country. However, the harbor hinterland has been a refuge during the war in the past, and it has been concentrating on development related to the port industry; hence, it has a poorer residential environment. Therefore, in this study, in order to ensure equal development in space and equal access to basic urban services, urban design directions were suggested for the harbor hinterland based on the concept of an inclusive city'. To this end, through factor analysis, urban planning elements that can be applied to urban design were derived, and through PLS(Partial Least Square)regression analysis, based on the opinions of residents and experts, urban design directions for the port hinterland were presented. The study site was Gamcheon Port, one of the Busan Ports in Korea, the hinterland of Gamcheon Port was a high slope, and the residential environment was relatively poor due to the dense concentration of older residential areas.

  • Countries in the world make a strategic effort to develop their own ports into hub ports and lure transshipment cargoes. Likewise, the Busan Port tries to become a container hub port in Northeast Asia, but there is lately a gradual decline in the number of transshipment cargoes. The purpose of this study was to examine the influential factors of port transshipment traffic in an effort to identify the determinants of transshipments in the Busan Port. In existing studies, harbor infrastructure, maritime transshipment cost, port cost and port service were primarily presented as the determinants of transshipment traffic after surveys were conducted by experts. In this study, the transshipment traffic in the Busan Port was selected as a dependent variable, and the container traffic and transshipment traffic of ports in adjacent countries and each country's amount of trade and economic growth rate were selected as explanatory variables to analyze what factors determined the transshipment traffic in the port.

  • Recently the first stage qf construction for Busan new port emerged over the sea surface at the north container terminal site. With this, there are lot of discussions and debates on increasing the water depth at the approaching channel and mooring basin from the existing 15m to 18m by dredging work in order to be able to serve 12,000TEU containership, and at the same time, correction to the reclamation plan of hinterland at the part of Undong Bay qf the new port site. Since the attack of typhoon 'Maemi' in 2003, it is expected that the design wave parameters for coastal and harbor structures in this area would be somewhat changed and so the extreme wave condition at each terminal and tranquility of berthing area does, and therefore, it is necessary to analyze the tranquility at each berth Hence in this study, we constructed a wave model for these conditions and performed simulation together with the circulation model simulation, compared with the field data collected The result showed the increase of the harbor response throughout the basin but not severe condition However, a certain location needs to be prepared for the rough sea condition when a severe typhoon hit the site.

  • Busan Port handles more than 75% of the domestic freight volume and is ranked at 6th for global shipping in the world. This paper aims to estimate ship emission in North Port that is the center of Busan Port and located near the residential area. The emission for each type of ship is calculated applying a emission model proposed by U.S. EPA and the atmospheric diffusion pattern of the exhaust gas according to the season, the weather condition and the time was identified using CALPUFF Model. As a result, the major pollutants of $NO_x$, $SO_x$ and PM10 were 30,853 tons, 36,281 tons and 6,856 tons, respectively, and the highest rate was 42% in oil tankers. On clear days, air pollution was stagnant around the harbor, spread widely on windy days, and tended to be thinner on rainy days. The research contributes to recognizing the seriousness of air pollution and can be used as basic data for policy making in the future.

  • Recently huge typhoons had attacked to the coastal waters in Korea and caused disastrous casualties in those area. There are some discussions on correction to the design parameters for the coastal structures. Wave transformation computations with the extreme waves are of value in planning and constructing engineering works, especially in coastal regions. Prediction of typhoon surge elevations is based primarily on the use of a numerical model in this study, since it is difficult to study these events in real time or with use of physical models. Wave prediction with a two dimensional numerical model for a site with complicated coastal lines and structures at the period of typhoon 'Maemi' is discussed. In order to input parameters for the extreme wave conditions, we analyzed the observed and predicted typhoon data. Finally we applied the model discussed above to the storm surge and extreme wave problem at Busan Harbor, the southeast coast of Korea. Effects of water level variation and transformation of the extreme waves in relation with the flooding in coastal waters interested are analyzed. We then mack an attempt to presen a basic hazard map for the corresponding site.

  • There are two major types of underwater blasting at Korea, bridges and harbor construction work. Pier blasting for lay the foundation bridges construction is used dry excavation working (drilling and charging) after pump out water and then fire pump in water that is same as bench blasting. In contrast, underwater blasting for harbor construction and increase of harbor load depth is used to barge with digging equipment that is in oder to drilling on the surface and blasting work(charge, hook-up) under water. Thus, there are need to special concern such as charge method and hook-up method different from tunnel blasting work and bench blasting work. If do not use special concern breaks out dead pressure and mis fire because of there are so many difficult condition such as water pressure, obstruct field of vision. In this study underwater blasting at Busan Harbor Construction have consider with special concern that is plastic pipe charge method used to MegaMITE I and specialized buoy hook- up method make far initial system detonate on the surface used to TLD. The results is designed blast pattern charge per delay effect an inspection of verify between predict velocity and measure velocity. minimized break out mis fire consideration charge method, hook up method. According to result best underwater blasting design is 105mm drilling dia, MeGAMITE II, HiNLL Plus(non electric detonator).
