【摘要】 深基坑开挖对周围地下管线影响规律的研究 ,是基坑环境工程中的重要课题。本文在Singhal研究的基础上 ,充分考虑基坑围护结构、土体和地下管线变形耦合作用 ,运用三维有限元法 ,求解了受基坑开挖导致的柔性地下管线位移和内力 ,为基坑环境工程研究提供了一定理论依据和实践指导作用。更多还原

【Abstract】 The response of the jointed ductile pipeline to the deep excavation in soft soil is studied in the paper.The effects of the deep excavation on a underground pipeline in soft soil are an important project in environmental engineering.A 3-D finite element method is used in the study.The displacements and internal forces of the jointed ductile pipeline are obtained based on the Singhals study.It is induced by deep excavation.Such as the coupled action of the retaining structure,soils,and pipeline are taken into consideration.Some useful conclusions are obtained through the study更多还原
