Through simulation , found the influence rule on existed structure by shield construction , discussed construction factors such as soil deformation modulus , different thickness of and different elastic modules of equivalent circle zone , control soil pressure , initial stress release rate influence on the surface settlement and structure deformation , studied the reasonable parameter value scope

It is not always good at increased the cement ratio ; sometimes it is even harmed to the strength of the pile . the strength of the pile must matches the strengths of the origin soft foundation . improved fixing methods of strain meter and how to calculate the deformation modulus , the load transfer behavior of cement - soil pile , the compound foundation bearing capacity , pile - soil stress ratio with the increasing of the load are analyzed and studied
