摘要
针对重庆地区层状岩地层超大断面车站拱盖法施工的沉降问题,以重庆地铁5号线凤西路站拱盖法施工为研究对象。通过建立三维分步开挖模型进行全过程数值分析,将计算值与实测数据进行对比,探明了双层叠合初支拱盖法施工关键步序为拱部中导洞开挖,并进一步提出了拱顶沉降分步控制标准。
According to the settlement of the construction of the super large section station arch cover method of the layered rock strata in Chongqing area,the construction of Chongqing Metro No.5 Feng-Xi Road station arch cover method is the research object.Through the establishment of 3D excavation model for numerical analysis,the calculated value and the measured data are compared,proven double stacked together primary support arch cover construction key procedure for arch,excavation and further puts forward the vault settlement step control standard.
