Construction Method of Current Controlling Length of Cement Mixing Pile and CFG Pile for Soft Soil Subgrade

Abstract:

Passenger railway line of Xiamen-Shenzhen railway has lots of soft-clay sections. Reinforcement schemes of base soft clay include two forms, cement mixing pile and CFG pile. If reinforcement thickness of soft clay is inappropriate, it makes the base of the built subgrade construction settle and deform. The paper uses ammeter to dymatically control the length of cement mixing pile and CFG pile, which not only effectively ensures that all reinforcing pile shafts can enter bearing stratum, but also improves foundation capability and avoids settlement and deformation of foundation.
