Study on Settlement and Deformation Laws and Control Measures of Rectangular Pipe Jacking Construction for Metro Entrances and Exits:A Case of Jinan Metro Line 4 Duandian Station
摘要
Abstract
In view of the large settlement impact on the surface during the construction of rectangular pipe jacking,FLAC 3D software was used to simulate the actual excavation process of rectangular pipe jacking dynamics,to explore the influence of construction sequence on the surface during the construction process,and to analyze the settlement amount of surface and underground pipelines during the construction process,so as to ensure the normal and safe construction.Taking Jinan Rail transit Line 4 as an example,this paper analyzes and summarizes the actual situation and then puts forward the reasonable construction schemes and solutions.关键词
