劲性搅拌桩单桩工作特性

Analysis for Performance Characteristic of Concrete-Cored DCM Pile

劲性搅拌桩是1种用于处理软土地基的新型桩,是在水泥土搅拌桩中即时插入高强度的内芯桩形成的复合桩．对劲性搅拌桩荷载传递特性进行了分析；并结合劲性搅拌桩的成桩特点,通过原位试验的研究,对该桩的几种破坏模式进行了研究、分析．

Concrete-cored DCM pile is a new kind of composite one that is developed for the ground treatment in soft clay ground. The composite pile is composed of an external DCM pile socket and an inner precast concrete pile that is inserted right after the completion of the DCM pile. This paper will first analyze the load transfer characteristic based on the characteristic of practical material. This paper studies the failure modes for concrete-cored DCM pile using the data from in-situ test.
