摘要: 本文根据北京地铁复兴门折返站工程开挖全过程中隧洞侧壁土体水平位移观测结果,结合其它工程的观测资料,分析了浅埋隧洞注浆开挖全过程中土体水平位移的一些规律。初步探讨了如何运用测斜仪在施工过程中进行安全观测的问题,并从水平位移这个角度评价一种先在土体中注浆然后采用新奥法施工的新施工方法。
Abstract: The horizontal displacements are monitored during excavation procedure in the sidewalls of Fuxingmen Station, a returning tunnel of Beijing Subway buried in soil media. Based on these results with those obtained from other engineering projects, the characteristics of horizontal displacement are analyzed in shallow soil tunnels during grouting and excavation procedure of the tunnels. The usage of inclinometer for construction monitoring is studied primarily, and a new underground construction method in soil media, i.e., grouting prior to NATM construction is assessed.
