摘要
以双流机场隧道深基坑监测资料为基础,结合施工情况对施工过程中围护桩应力、位移的变化规律及主要施工工序、开挖深度、斜坡荷载对围护桩应力、位移的影响规律进行了分析,在此基础上提出了施工过程中提高基坑稳定性的措施。文中所述结论及建议对类似工程有一定借鉴指导意义。
Based on the monitoring data on deep foundation pit of Shuangliu airport tunnel and combined with construction situation,the paper analyses the fenderpost stress,evolution laws of displacement,major construction procedure,depth of excavation,stress on fenderpost from slope loading and displacement influence etc.in the construction process.On that basis,measures for raising foundation pit stability are proposed,which may be referenced by similar projects.
