摘要

某轻轨隧洞相临重庆市某高层建筑（水晶城堡）岩体地基，采用工程地质定性分析、附近同类工程建设的经验类比、三维弹塑性有限元数值分析等多种技术手段

对拟建建筑和地下轻轨隧道的相互影响及其稳定性进行综合分析与评价，全面分析了修建高层建筑对轻轨隧洞围岩位移、应力及对其安全系数产生的附加影响。分析表明

修建上部建筑物对地下洞室的开挖位移和应力有微量扰动，洞顶最大附加位移量为1.15 mm，塑性区变化不大，由此可认为在正常施工和工程地质情况无异常的情况下，该工程的修建不会对地下洞室的安全和围岩稳定性构成影响，可为同类地下工程建设提供一定参考。

Abstract

The construction of underground project or the underground tunnel will influence the subsiding of adjacent building on the earth surface. One urban underground tunnel is adjacent to a high-rise building called Shuijingchengbao. By using three methods that are qualitative analysis of engineering geologic

experience analogism of adjacent similar engineering constructions and 3D finite element method (FEM)

the interaction and influence between the tunnel and the adjacent structure was synthetically analyzed and evaluated. The result indicates that the structure’s building has neglectable disturbance to the displacement and stress of underground tunnel

the maximal vertical displacement of tunnel roof is only 1.15mm and the change of plastic zone is tiny. Hence

it can be justified that the building of the engineering is unlikely to influence the safety and stability of surrounding rock of the tunnel without abnormality construction and exceptional engineering-geology. It can offer a theoretical reference to the construction of the underground engineering.
