Three-dimensional Numerical Analysis of Environmental Deformation Effect Considering Different Grouting Effects
Grouting effect is the key influencing factor of environmental deformation during pipe jacking construction.In this regard,a three-dimensional numerical analysis model of pipe jacking is established.By distinguishing the friction coefficients under different mud distribution conditions,the influence of different grouting effects on environmental deformation during pipe jacking construction is studied.The results show that the soil disturbance directly above the pipeline is greater than that on both sides during the pipe jacking construction;the complete mud casing can effectively reduce the soil loss and the back soil effect;the better the grouting effect and the more complete the mud casing,the more it can reduce the surface settlement and pipe displacement during construction.
