摘　　要：以广州市大观路与车陂路系统改善工程中新建下穿东环快速路的隧道为工程背景,分析软弱围岩下浅埋大断面的市政隧道近距离穿越快速路的沉降和隧道围岩收敛情况,其计算结果可为同类工程设计和施工提供一定的理论依据。From the engineering background of a new-built tunnel which crosses under the Guangzhou east gate expressway in the improvement work between the Daguan Road and the Chebei Road,we are about to analyze the subsidence of this shallow tunnel and the convergence of the surrounding rock around it,which is surrounded by weak surrounding rocks and located near the large fracture section.The result of the calculation in this analysis can provide some certain theory evidence to the engineering design and construction of homogeneous engineering works.
