摘要
为解决不同岩性接触带下暗挖隧道小净距施工存在的问题,以某城际车站为工程背景,考虑其周边环境、地质及水文条件等影响因素,主要采取两项技术措施:通过分析不同岩性接触带下的地下水渗透特点,确定适宜的加固措施;通过建立合理的有限元模型,对小净距暗挖隧道进行数值模拟分析,从而确定合理的施工步序及技术措施。
In order to solve the problems existing in the construction of small clear spacing of underground tunnel under different lithological contact zones, two technical measures are mainly adopted by taking an intercity station as the engineering background and taking the influence of its surrounding environment, geological and hydrological conditions and other factors into consideration. The appropriate reinforcement measures were determined to solve the problem of groundwater reinforcement by analyzing the characteristics of groundwater seepage under different lithological contact zones. The numerical simulation analysis of small clear spacing underground tunnel was carried out to determine the reasonable construction steps and technical measures through the establishment of reasonable finite element model.
