Shield construction method has been dominant in the subway construction , land subsidence caused by the construction and the impact on the surrounding environment is very concerned about the problems in the design and construction of the tunnels . The city shield tunnel construction often have to cross the underground pipeline , underground pipeline is the lifeline of the city , including water supply, drainage , electricity , telecommunications , gas supply, underground pipes , shield tunneling via pipeline must ensure safety . Thus, accurate analysis of ground deformation caused by the calculation shield construction , the stratum deformation of the pipeline by the force and displacement , the calculation of the force and displacement of the pipeline . In this paper, the Wuhan Yangtze River Tunnel Shield construction of underground pipelines subject to numerical analysis method , select the Wuchang Peace Avenue underground pipeline as analysis object , using the finite element software ABAQUS may cause dangerous pipeline three-dimensional numerical simulation of shield tunneling . In the modeling process , considering the nonlinearity of the soil , soil stratification , soil and the lining of the interaction , pipeline analysis , consider the the shield construction cutterhead propulsion , grouting pressure shield open dug from the pipeline distance , the main factors of the interaction between the double hole pipeline depth , summed up the general laws of the disturbance and deformed strata , left and right lane tunnel has excavation , pipeline displacement and force a general rule, a reasonable choice shield construction parameters to minimize the disturbance to be caused by the construction of the strata and pipeline . Predict the force and deformation of the pipeline , and the allowed values ??, to determine the security of the pipeline , the proposed pipeline protection . The conclusions and recommendations of the tunnel shield construction and pipeline protection has theoretical and engineering guidance value .
