Study on Simulation of Ground Deformation Caused by Shield Construction Based on Analysis of Multi-factor
2013
Ground deformations induced by tunneling is not only affected by rock soil media conditions,but also affected by the other factors(i.e.,tunnel geometry,shield operations and construction environment).Taking Wuhan subway line 2 as the background,the influence factors on effects of the deformation in tunneling are investigated based on the measured deformation data.And the ground deformations decomposed into trend deformation and stochastic deformation.The nonlinear relation between influence factors and ground is established.Meanwhile,an improved intelligent method is employed to identify the nonlinear system.And a multi-factor dual-mode intelligence analysis system(MDIAS) is constructed.The deformations are simulated by the MDIAS based on the variation factors.It is shown that MDIAS can not only preferably reflect the various factors in deformation calculation,but also dynamical simulate the deformation evolution in the complicated condition.MDIAS is an effective tool for estimating soil deformation.
