【摘要】 结合上海某住宅小区软粘土地层的打入桩施工工程 ,采用Winkler弹性地基梁理论对地下管线的变形控制值进行计算分析 ,并通过无限长小孔扩张原理对打入桩施工对引水渠的影响进行了计算 ,在此基础上提出了采用卸压孔对引水渠进行保护 ,并对在打桩施工过程中引水渠的变形进行了监测分析更多还原

【Abstract】 In this paper the deformation control values for underground pipelines were analyzed with Winkler theory and the soil squeezing effect was calculated with principle of small hole expansion. Based on above given, the discharge hole for earth pressure was used to protect the underground pipelines in the project. The monitoring was carried out on deformation of underground pipeline during pile construction.更多还原
