摘要
某隧道衬砌为复合式衬砌。地形起伏较大,周边居住人口较多,尤其洞顶民居密集,施工场地小,对于施工安全、环境的保护及水土保持有相当高的要求。为了解决因震动过大而导致隧道附近建筑物产生沉降和坍塌和因施工场地噪音过大而对周边居民造成生活干扰两大难题,提出一种噪音小、沉降小的隧道施工方法。
The lining of a certain tunnel is a composite lining.The terrain is undulating greatly,with a large number of surrounding residents,especially the densely populated residential areas at the cave top.The construction site is small,and there are quite high requirements for construction safety,environmental protection,and soil and water conservation.In order to solve the two major problems of settlement and collapse of buildings near the tunnel caused by excessive vibration and interference with the living of surrounding residents caused by excessive noise in the construction site,a tunnel construction method with low noise and settlement is proposed.
