  • Although the construction noise and vibration are transient and intermittent, their impact on the surrounding environment is huge. Since the construction equipment noise and vibration is usually transmitted because of the long distance, the sound insulation and the proper design of anti-vibration measures are very difficult. The regulation requires that the noise and vibration caused by the construction equipments should be measured within 30m from the source, whereas the blasting noise and vibration should be measured at least 60m and 160m away from the source, respectively. Instead of the 2D modelling mainly conducted so far, the 3D analysis of noise and vibration with the consideration of the height and size of the building, mountains and hills in the vicinity of the source is necessary.

  • 건설공사장 소음·진동 문제는 공사규모의 확대 및 대형중기의 사용으로 인하여 피해가 확대되고 있다. 특히 최근에 도심지 공사의 빈도가 증가하면서 대부분의 경우 인근 주민에게 피해를 줄 수 있는 법적 기준을 초과하고 있고, 소음에 노출된 주민들의 의식 변화로 많은 민원이 야기되고 있으나 현행 국내의 건설소음 진동 규제기준이 대상지역별, 시간대별로 전체적인 레벨만을 제시하고 있어 효율적인 대책수립이 어려운 실정이다. 또한 토목공사의 경우 공사현장과 가축양가 사이에 분쟁이 발생되고 있으나 인과관계의 성립여부, 피해규모, 피해액 산정, 향후조처 등에 대한 명확한 기준과 처리 사례가 국내외를 막론하고 극소수에 분과하여 분쟁의 조정이나 대책수립에 많은 어려움이 있다. 따라서 본 논문에서는 소음진동에 관련된 법적인 기준이나 각종 물적 피해에 대한 판정기준을 설명하고 당사 현장에서 발생한 민원에 관련된 사례를 소개함으로서 현행법의 문제점과 원활한 공사진행을 위한 민원에 대한 의식을 높임으로서 공사초기에 적극적으로 대처하게 하여 원만한 공사진행에 도움이 되고자 한다.

  • Presently, working gas pipelines are being subjected to the influence of construction vibration. Especially on subway and road construction, gas pipelines are being influenced to construction vibration caused by use of construction equipment, passage of a large-sized vehicle and blasting. Buried gas pipelines are subjected to the influence of vibration caused by blast in the vicinity of pipeline, exposed gas pipelines are subjected to the influence of vehicle vibration. Therefore, in the study, it is developed to vibration prediction program of gas pipeline by analyzing measured construction vibration. This program is able to predict vibration of gas pipeline according to field conditions by using the results of structural finite element analysis and empirical equation by reliability analysis. And, this program contains the database of construction vibration. Additionally, this program is able to compute estimated blast vibration equation using measured blast vibration data in the field and to form graph of allowable charging gunpowder per delayed-action with the change of blast velocity. Therefore, field workers are able to predict construction vibration around gas pipeline and estimate safety of gas pipeline.

  • A Basic experimental study for the development of vibration-power generation system from the vibration energy of urban infrastructure, such as a railroad, highway, and bridges, was carried out to harvest electricity from moving vehicles. Starting with the proposal of vibration power generator which converts vibration energy to an electric power by using self-induction technology, the research explains the basic concept of self-induction technology and the dynamic characteristics of a ibration power generator. Also, in order to analyze the correlation of an electromotive force from vibration power generator which depends on external force and vibration speeds, many indoor experiments with various variables were achieved. Based on the experimental results, a vibration power generator system's ability were analyzed. With those results, basic data of vibration power generator system to acquire the maximum available power was confirmed.

  • Property development along railway lines is a critical issue at present. Because various railway lines exist in most large cities, there are numerous properties and open spaces to be developed for communities associated with these lines. The active development of railway properties can be a means to resolve housing shortage problems in cities. In this first part of this paper, noise and vibration levels of an artificial area of land and apartment complex are measured and evaluated to derive a design strategy for vibration reduction purposes.

  • Recently, with the development of construction machinery, low-vibration construction machine such as Tricone-Bits, which can drill both soil and rock layers and minimize vibration, is being used frequently. However, although many studies have been conducted on the prediction of vibration values for earth augers and pile drivers, the reality is that studies on the effects of vibration on low-vibration drilling equipment are lacking. In this paper, ground vibration values for Tricone-Bits were measured, and a vibration distance damping formula was proposed using this. In addition, after predicting the vibration of the earth auger and pile driver using the previously proposed vibration distance damping formula, the degree of vibration damping for the Tricone-Bits was evaluated by comparing and analyzing it. As a result, the Tricone-Bits showed a vibration reduction effect of 97% and 93% compared to these machine and It will help with management and prediction of the ground vibration effects evaluation on the low-vibration equipment such as Tricone-Bits.

  • 현재 우리나라에는 다양한 사회간접자본의 건설이 실행되고 있다. 사회간접자본의 건설은 국가의 장기적인 성장을 위하여 필요한 공공적인 사업이지만 필수적으로 대형의 건설작업이 수반하기 마련이다. 이미 인구의 집중도가 높은 도시지역은 물론이고 농어촌지역에 이르기까지 이들 건설사업으로 인한 진동과 소음 문제로 민원이 끊이지 않고 있는 형편이다. 특히 오랜 개발도상의 기간에 일방적으로 보호되지 못하였던 시민의 권리가 요지음 집단민원의 제기라는 형태로 표출되었고 이 과정에서 진정한 민원피해의 발생여부를 가릴 수 있는 기준이 필요하게 되었다.
