  • 건설사업과 환경보전은 대립적인 요소를 많이 가지고 있어 건설사업으로 인한 환경 분쟁이 급증하고 있으며 소음 $\cdot$ 진동에 관한 분쟁이 대부분을 차지하고 있다. 이러한 분쟁과 민원은 기업에 대한 부정적 이미지, 사업의 지연 $\cdot$중단, 배상액 지불 등 막대한 경제적 손실을 가져오므로 치밀하게 관리할 필요가 있다. 본 논문에서는 문헌조사를 통하여 이론적인 고찰을 실시하고, 소음 $\cdot$진동 관련 법령을 정리 분석하여 건설사업과 관련된 검토항목을 추출하였다 또한 사전 환경성 검토 환경영향평가 항목과 분쟁조정에 관한 통계자료를 검토 $\cdot$분석하여 건설사업의 추진단계별 소음 $\cdot$ 진동 관리방안을 제시하였다 이는 건설사업을 수행함에 있어서 소음 진동에 관한 규제사항의 정확한 준수와 분쟁 및 민원의 발생을 최소화하는데 활용될 수 있을 것이다.

  • The cooling system, including a fan is a one of the major sources to generate the radiated noise of construction equipment. Therefore, it is required to reduce the flow noise induced by a fan in order to reduce the noise level. In this study, we made an engine room model to carry out a variety of experiments. And then, the flow noise analysis technique using the CFD code was applied to the cooling system of construction equipment. These analyses results agree well with the measurement results. These results make it possible to understand the flow noise characteristics and to design the low noise cooling system in the design stage.

  • In downtown, construction noise related claims are the most important issues. Sometimes noise related claims halt the construction process. Therefore, Introduction of noise reduction measures is common to construction process with a loud noise. This case is about concrete pouring for mat foundation of super tall building. Concrete pouring process using High Pressure Pumping machine causes high noise level in the vicinity of area. And large number of transit-mixer truck cause traffic congestion. This paper introduces effort and process to prevention of construction noise claims on massive scale concrete pouring.

  • The noise emitted from construction machinery has long been a cause of environmental disputes, especially to the nearby residents. In 2008, the Ministry of Environment adopted the construction machinery noise labeling system to encourage the development of the low noise construction machinery. After the implementation of the noise labeling system of the construction machinery, the noise emitted from the construction machinery has been decreased over the six years. But, as the quality of life improves, a growing number of people desire more comfortable and quite living environment. Under the situation, new systems like the low noise labeling system are considered to encourage the development of the low noise construction machinery. In accordance with the low noise labeling system, the construction machinery satisfying the standard of low noise are qualified to attach the low noise label in front of the products. Thus, the product qualified the low noise certification will be incentivized by the choice of the consumer. In this paper, we have studied the necessity of the low noise labeling system for the construction machinery and the considerations to adopt the low noise labeling system of construction machinery. And we have studied appropriate criterion to judge the low noise construction machinery. The considerations studied in this paper will be helpful to adopt the low noise labeling system of construction machinery in the future.

  • In this study, the SIP (Soil-cement Injected precast Pile) method among the Low-vibration & Low-noise pile driving methods was decided into study compensation. Ground vibrations by the SIP methods step by step divide and were analyzed. Quantitative response values and ground vibration equations with reliability were presented from findings of this study. Also, vibration responses that are occurred by the SIP method of construction were compared as quantitative with vibration responses by general method of construction that are presented in existent study. Ground vibration values by the SIP method correspond to level of 17 ~ 57% of values that are assumed by the Attewell & Famer's equation, respectively, and these result compares in reliability 50% and separated distance 10 ~ 50 m. Also, those values were analyzed that correspond to level of 14 ~ 96% of ground vibration values by the Prof. Park's equation, respectively. Construction limit extents, separation distances from vibration occurs position, were presented that can satisfy domestic criteria for vibration control for the SIP methods. Those presented in this paper were divided newly according to reliability.

  • Nowadays, the construction sites are growing in city every year, so complaints for construction noise have increased more and more. To analyze this noise scientifically, construction noise prediction program was developed in 1998 and 2005 but it is too difficult to apply program in field because there is few soundproof facilities and it can't understand the coordinate system and so on. The aim of this study is to develop noise prediction program to apply in construction sites. For this, the problems of existing program was analyzed and survey was performed to get requestion of field overseer and upgraded program. To get reliability of program, it was compared with sound measurement value in field. As a result, construction sound prediction program have various soundproof facilities data than existing program. It can also analyze multi receiver point at the same time for several construction machinery. Most of all, it is more powerful to set receiver or source in the axis of X, Y, Z. so program user can make use of it easily. An average of difference is -0.9$\sim$1.8dB.

  • The energy efficiency and environment-friendly aspect of the railway system would be superior to other on-land transportation systems. In a preliminary feasibility study stage, the energy efficiency and problems related with environment are usually not considered. The railway noise and vibration which could be reasons of environmental problems are focused and studied in this paper. The investment for railway systems could be encouraged by the considering of main environmental elements evaluated with the modified noise and vibration standard for environment-friendly railway construction.

  • 본 연구에서는 암반의 굴착(발파)공사 등으로 인하여 발생되는 지반진동과 어패류 양식장 등의 수중 배경소음도 및 실제 발파작업시에 발생하는 수중 대상소음도의 척도를 비교 분석하고, 회귀분석에 의한 지반진동추정식과 수중 대상소음 간의 상관식을 도출하여 굴착공사시 수중소음도의 발생정도를 사전 예측하고자 하였으며, 나아가 수중소음 관리기준의 정립을 위한 첫걸음으로 본 연구를 시작하게 되었다. 그동안 실험을 진행하기 전에 상황조건을 달리한 어패류 양식장에 대해 배경소음도를 측정하여 본 결과 양식장마다 각각의 환경적 특성에 따라 배경소음 수준정도가 다양하게 나타나고 있고, 수중소음을 유발하는 지반진동을 실측하여 지반진동과 수중 대상소음 간의 상호 관계식을 도출할 수 있었다. 따라서 상관식에 의해 각종 건설공사에서 수중소음 유발정도를 사전에 예측하여 당해 실정에 적합한 관리(허용)기준을 설정, 설계 시공 등에 적용할 수 있으므로 과거의 기술적, 공학적 논리의 빈약한 기술전개로 인한 어패류 피해의 경제적 손실을 사전에 예방할 수 있고, 수중생물체에 대한 안전성을 확보한 가운데 원만한 건설공사를 진행할 수 있다는 가능성을 발견할 수 있었다.

  • In case of the construction equipment using by the military camp, such equipments are different from those equipments using at general construction site, of which muffler(silencer) is attached at the passenger seat side, since such equipments are obsoleted, it is great part that a considerably loud noises are continuously diffusing. When working, such noise can be influenced a lot of effects to those working soldiers nearby the equipment, and though it is really terrible loud noise as much as can arise a civil complaints by neighboring civilians, but because its specialty of the military, it is real state that there are many difficulties in establishing an effective soundproof countermeasure due to study shortage and lack of the relevant material regarding to military construction equipment. Accordingly, this study has ever grasped the characteristics of noise by its each frequencies and by distances about those 9 kinds of construction equipments using chiefly by the military camp. As the result, it was known that the military construction equipment is generating the loud noise which can influence bad effect to the workers, and such high sound pressure level of low frequency band can harm even to far distance.
