THE SUBGRADE TECHNIQUE OF CFG PILE COMPOSITE FOUNDATION

摘要

The high-speed railway in soft soil region is constructed rapidly, the CFG pile composite foundation in treatment of soft soil foundation is applied widely and successfully.This kind of foundation has many advantages in high bearing capacity, convenient construction, low costing,strong adaptability and easy quality control.In order to have a further study of this kind of subsoil treatment technology, the paper discussed the basic principle of CFG pile composite foundation, the engineering conditions, construction technique and the in-situ static load test.Some conclusions about CFG pile composite foundation are listed in the paper.
