Granular Compaction Pile are commonly used to improve bearing capacity and reduce settlements of soft soil in coastal and lowland areas. In this paper, through the field load test results of straight granular compaction piles and taper granular compaction piles, material properties of ground and GCP for numerical analysis were drawn and numerical model was established. In the numerical analysis of taper granular compaction piles with 3 different sections, a optimum dimension of taper granular compaction pile was considered at the side of settlement.
