When highly compressible, clayey soil layers lies at a limited depth and large consolidtion settlements are expected as the result of construction, precompression of soil may be used to minimize postconstruction settlement. In this study, we tried to find the possibility about the effect of ground improvement using flat dilatometer at the Inchon International Airport where preloading was installed. Field and laboratory tests were performed for soft ground before and after preloading in order to check the effectiveness of the soft ground improvement and compared with the test results of dilatometer which obtained before and after preloading at the same location Field tests such as flat dilatometer, vane, CPTu tests were performed before and after preloading and undisturbed samples are obtained to carry out laboratory tests. As comparing results, after preloading, unit weight, effective stress, undrained shear strength were increased and we can also check the decrease of consolidation late caused of decrease of void ratio. Furthermore, it is assumed that the possibility on the effect of ground improvement by using the flat dilatometer

Piezocone test as well as Dilatometer tests are used worldwide to evaluate the engineering properties of clay soils. The common strong point of the two tests is that they can estimate, by the identical test equipment, various properties of soils, which are the unit weight of soils of OCR, K$\sub$o/, undrained shear strength(s$\sub$u/), coefficient of consolidation(c$\sub$h/) and soil classification etc,. A series of the two types of field tests are performed in this study on marine clays with low plasticity at Inchon International Airport construction site to estimate various properties of the soils such as s$\sub$u/, OCR, and c$\sub$h/, which are then compared each other as well as with the results of reference tests. The comparisons show that the way of interpretation is the most critical factor in obtaining confidential results for a certain engineering property for both tests.

An Airport is important space and even stands for the country because diverse people from other countries use a variety of facilities in the gateway to the country. Therefore, It is urgent for those people to increase efficiency and convenience of its usage. But we have a problem with process of passenger and this paper with the object of finding the solution in case study. This paper focus on information system, especially Intelligent Airport Information System to streamline process of passenger. There are a few of countries adopted this system in process. Therefore, IIAC(Incheon International Airport Corporation) establishing u-Information HUB System. It is unique and differential characteristics to Facilitation and increase passenger's satisfaction. u-Information HUB system unified stakeholder's process of Facilitation in Air Traffic Sides. u-Information HUB system gets the highest state of efficiency to Facilitation. This Paper is attempt to find new effort

After analyzing each procedure from standard instrument procedures used at Incheon International Airport, which is believed to have caused noise problems in and around Ganghwa island, we came to a conclusion that some Standard Instrument Departure Procedures and Standard Instrument Approach Procedures need to be revised, and therefore we made some propositions with regard to noise abatement procedures(CDA, RNAV approach etc.). Additionally, we evaluated viability of the proposed flight procedures by conducting a number of demonstrations with use of flight simulation.

In this Paper, concrete durability, coefficient variation of compressive strength, and hydration heat development characteristics of concrete using different types binder for 2nd Phase Construction in IIA were investigated. The experimental results show that the coefficient variation of compressive strength decreased with the slag cement when compared with the replacement of granulated blast furnace slag powder. And the diffusion coefficient of chloride ion decreased with use of a blended cement when compared with using a only portland cement. Also the type of low heat cement is very suitable to reduce the thermal crack caused by hydration heat development.

The aim of the study is to investigate the factors which decide an airport service quality and the differentiation of perception on the airport service quality between airport users and airport authority. For the purpose of this study, the determinants of airport service quality were factors analyzed on the basis of service marketing concept. In order to identify an airport service quality dimension, the writer conducted mail survey and individual interview from the Korean freight forwarders, the 3PL entities, integrators and the airport operation authority. The result of this study is summarized as follows. 1. The dimen measurement was confirmed as a superior method to dimension of service competitiveness.sions of airport service quality consist of five factors; tangibles, reliability, responsiveness, assurance, empathy. 2. There are notable differences in cognition of airport service quality between airport authority's perception and airport customer, and between airport customer's perception and expectation.

This paper describes the unified reliability evaluation with partial loss of continuity for Inchon international airport distribution system which is complex and difficult system to implement. To evaluate reliability considering line limitation and voltage drop of the system, PLOC technique which is based on deterministic evaluation technique and failure mode & effective analysis method is employed. And reliability indices calculation method is used. Finally, to evaluate the system performance and to improve the reliability of the system, Analytic network process method is employed. As a result, calculating accurate reliability, finding weak points, and expansion scheduling of the system is possible.

After a series of aircraft noise measurements conducted in Noise Sensitive Areas(NSAs) in Gangwha Island, there appeared to be no regions affected by aircraft noise of over 75 WECPNL, the legal noise level standard for aircraft operations. However, with regard to the future environment where flight operations at Incheon International Airport are likely to escalate, an INM analysis result drawn shows that the number of regions afflicted by such noise will increase in Gangwha Island. Therefore, we studied similar cases from developed countries, which are pertinent to solutions for aircraft noise abatement in the vicinity of airports and herewith provided 6 more flight operation procedures other than those 3 currently in service at Incheon International Airport.

The purpose of this study is to analyze the economic aspect of sea transportation system between Inchon and Youngjong island in which Inchon international airport is being constructed. Total demand of sea transportation arising from in the airport and Yongyu Muwi leisure complex was estimated. To select optimum transportation route, environmental conditions in and around Inchon harbour and Youngjong island including the change of water depth by tide current, fog, rain, wind adn typhoon, ets., were investigated. The preliminary consideration on ships (size, velocity, transport capacity, price), routes, operational modes, terminals and berthing facilities were carried out. The transportation cost per passenger by sea transportation system was estimated to compare with that of land transportation system. It was found that sea transportation system proposed is competitive to the transportation system.
