摘要
深层水泥搅拌-钻孔灌注桩(DCM-BP)是一种新型桩基复合地基,其加固机理的研究目前尚处于起步阶段,为研究DCM-BP桩在软土地区水平荷载下的力学性能,以实际项目开展了软土地区的DCM-BP满负荷水平向荷载试验,研究DCM-BP桩的加固机理及承载力、位移、弯矩等力学性能。研究结果表明,DCM-BP桩的承载力、刚度、弯矩等力学性能均要优于传统钻孔灌注桩(CBP)桩,为DCM-BP桩的力学性能研究提供了试验支撑。
Deep cement mixing bored pile(DCM-BP)is a new type of pile composite foundation,and its reinforcement mechanism is still in its infancy.To study the mechanical properties of DCM-BP pile under horizontal load in soft soil area,the DCM-BP full load horizontal load test in soft soil area is carried out with an actual project to study the reinforcement mechanism of DCM-BP pile and its mechanical properties such as bearing capacity,displacement and bending moment.The results show that the mechanical properties of DCM-BP pile,such as bearing capacity,stiffness and bending moment,are better than those of traditional bored pile(CBP).It provides experimental support for the study of mechanical properties of DCM-BP piles.
