Abstract

Concrete-cored deep cement mixing(DCM) pile is a new kind of composite pile used in soft ground engineering: it has many advantages such as simple in construction. little environmental disturbance

high bearing capacity，low settlement and less project costs. Based on the results from static loading test

the elastoplastic finite element method is used to analyze its much an ism under axial load

including pile-soil stress ratio (PSSR)

load transfer. load distribution between pile-core and p ile-socket。 plastic area in soils and pile head settlement characteristics

etc.
