Study on Predictin of Surface Subsidence of an Exremely Shallow Large-Span Double-Arch Tunnel

Li, Xin Zhi / Li, Shu Cai / Li, Shu Chen / Feng, Xian Da / Yuan, Chao / Li, Wen Ting

The Qi-Great Wall tunnel which crossed the Qi -Great Wall ruins was a large span double-arch tunnel with two-way and six-lane and the maximum depth was less than 5 meters, in order to protect the safety of thr surface ruins in the tunnel construction progress, surface subsidence control was particularly important. Through comprehensive geomechanical model test and numerical simulation , the surface subsidence wich generated in the process of construction according to construction methods of excavation and support was studied, the distribution of surface subsidence got through two methods was fitted well,and research results could provide guidance for the construction.
