某工程CFG桩复合地基沉降分析研究

Analysis and Study of Composite Foundation Settlement of CFG Pile of Certain Project

文章借助大型有限元ANSYS软件,考虑复合地基中各种材料的非线性特性,对CFG桩复合地基的沉降特性进行了有限元模拟分析,得出CFG桩复合地基随荷载、褥垫层厚度、褥垫层模量、桩间土模量和桩长变化规律。与工程实例相对比,对类似工程具有一定的参考价值。

In this paper, by ANSYS software considering the nonlinearity of the materials in the composite foundation, makes the numerical analysis of the settlement characteristics of the CFG pile composite foundation. The law that the settlement characteristics of the CFG pile composite foundation are affected by the load, the thickness of the cushion,the modulus of the cushion,the modulus of the soil between the piles and the length of the piles. Compared with the engineering case, has a certain reference value.
