摘要
结合实际工程,利用有限元软件对水泥搅拌桩复合地基的沉降进行了数值模拟,分析了桩距、桩长、桩体模量以及垫层模量对复合地基沉降的影响,得出了水泥搅拌桩复合地基的沉降的部分规律,对水泥搅拌桩复合地基的设计和施工有一定的指导意义。
On the basis of real engineering, the FEM is applied to anlyse numerically on settlement of cement-soil mixedpile composite foundation, and the factors including space among two piles, pile length, pile modular, underlying layer modular to effect on settlement of composite foundation are analyzed. The conclusions of settlement of cement-soil mixedpile composite foundation are obtained. The conclusions has guiding significamce for the similar engineerings.
