南干渠工程沿线的地下管线较多,地质情况复杂。通过对盾构施工的地质和管线情况进行综合分析,选出3段最不利的地质和地下管线工况,进行非线性三维有限元计算分析。分析盾构施工法对邻近地下管线产生的附加变形和附加应力,并据分析成果对地下管线进行安全评价。

Along the south main canal, lots of underground pipelines are available and complicated geological conditions encounter.Based on the comprehensive analysis on the geological conditions and pipelines where the shield tunneling is executed, three sections where most unfavorable geological and pipeline conditions are available are selected to carry out the nonlinear 3D finite element analysis and calcula-tion.The additional deformation and stress of the underground pipelines caused by the shield tunneling are analyzed.Furthermore, safety of the underground pipeline is evaluated based on the analyzing results.
