This study is investigated the extent of the noise and ground vibration in an adjacent zone of a cattle pen and an antiquated housing structures for judgement of the spot applicability on the extents of the noise and ground vibration of the rock-splitting method by an oil pressure. It is studied by measuring and analysing in an adjacent position the extents of the noise and ground vibration according to the work process of the rock-splitting method, such as drilling, rock-splitting, arranging rock, loading and by being compared with the permitted level on the noise and ground vibration fixed at the spot. To the results, it is identified that the influence to the noise has to be considered, even if the rock-splitting method is applied as an excavation method to lower a ground vibration by the classification on blasting method of the ministry of land, transport and marine affairs.
본 연구는 유압력을 이용한 할암공법의 진동 및 소음크기에 대한 현장 적용성 판단을 위해 축사와 노후된 주택구조물 근접지역에서 진동과 소음의 크기를 검토하였다. 검토는 할암공법의 작업과정별로 천공, 절개, 집토 및 상차에 따라 발생되는 진동과 소음의 크기를 근접된 위치(10m~80m)에서 측정 분석하여 대상지역에 설정된 진동과 소음의 허용수준과 비교 하였다. 그 결과 국토해양부의 발파공법 분류에 의해 미진동굴착공법으로 할암 공법을 적용하여도 소음도의 영향은 고려되어야 하는 것으로 확인되었다.
