地铁隧道下穿雨污水管线变形分析

摘要

Peck empirical formula was used to find the internal relation between ground surface or stratum settlement and pipeline interface deformation and to build the computation model for pipeline interface deformation.The Xitucheng station of Beijing Subway Line 10 which passes through under sewage pipeline was taken as an example to calculate the pipeline deformation value and compare it with the measured value,providing references for construction.%基于Peck经验公式,建立地表或地层沉降与管线接口变形的内在联系,同时建立管线接口变形的计算模型.并以北京地铁十号线西土城站下穿污水管线为案例,计算管线变形值并与实测值进行对比,为类似施工提供参考与借鉴.
