摘要
混凝土芯水泥土搅拌桩是适用于软土地基处理的一种新型复合桩,具有施工方便、造价低廉、单桩承载力高等优点。在静载试验的基础上,采用弹塑性有限元方法研究了该桩在竖向荷载下的力学性状,包括桩土和拉内外芯应力比,荷载的传递,桩侧塑性区分布以及沉降特性等。
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 mechanism under axial load, including pile-soil stress ratio (PSSR), load transfer, load distribution between pile-core and pile-socket, plastic area in soils and pile head settlement characteristics, etc..
