BEHAVIOR ANALYSIS OF BURIED PIPELINE RESPONSE TO NEARBY EXCAVATION PIT WITH BRACED RETAINING STRUCTURE
内撑式基坑工程周围地下管线的性状分析

The response of buried pipeline to nearby deep excavation in soft soil is an important project. The coupling actions of retaining structure,soil and pipeline are taken into account in this paper,and the behavior analysis of buried pipeline near deep excavation is obtained by three dimensional finite element method. The laws of buried pipeling response to deep excavation are related to many factors,such as the step of soil excavation,propping stiffness,depth of pipe below ground surface and the distance between pipe and excavation pit. The response results derived from the factors are obtained and compared,and some meaningful suggestions are proposed for engineering practice.
