摘要
Abstract
The research based on municipal tunnel project in Nanjing,on analysis of rectangular pipe jacking through the key cultural relics,the settlement mechanism in the process of rectangular pipe jacking is simulated and analyzed by using the software FLAC 3D.The research estimates the settlement value and main influence range of cultural relics and ground sur-face and puts forward the targeted design scheme and construction control measures.Numerical simulation and engineering practice show that extra-large section rectangular pipe jacking construction in complex environment has good effect on control-ling cultural relics and ground settlement deformation,and can meet the requirements of cultural relics protection in settle-ment;the simulation results basically accord with the settlement law caused by pipe jacking excavation,and the main disturb-ance range of soil in front and behind of pipe jacking occurs within twice the width of the tunnel;the transverse settlement curve shows a normal distribution,and the affected area is within three times the width of the tunnel;the pro-posed settlement control standard of cultural relics meets the requirements of actual construction and cultural relics protection,and can provide reference for similar projects.关键词
