【摘要】 为分析盾构隧道下穿供水管的安全影响，采用MIDAS GTS构建三维有限元模型进行分析，模拟了盾构隧道从靠近、下穿、远离供水管及完建运行的全过程对供水管安全的影响，得出了对其安全影响较小的结论。为管理单位提供了科学可靠的评判依据，为项目推进奠定了坚实基础，可供类似项目参考借鉴。更多还原

【Abstract】 In order to analyze the safety impact of shield tunnel passing through the water supply pipe, MIDAS GTS is used to construct a three-dimensional finite element model for analysis, and the whole process of shield tunnel from approaching the water supply pipe, passing through the water supply pipe, leaving the water supply pipe and completing the operation is simulated, and the conclusion that the impact on the safety of the water supply pipe is small is drawn. It provides scientific and reliable evaluation basis for management units and lays a solid foundation for project promotion, which can be used for reference by similar projects.更多还原
