板厚和外伸长度对平板式筏基沉降的影响分析

Analysis of the Influence of the Thickness and Overhanging Length on the Settlement of Plate-type Raft Foundation

本文主要分析平板式筏板基础的沉降问题。利用ANSYS软件建立平板式筏板基础有限元模型,通过改变筏板基础的板厚和筏板边缘的外伸长度,研究其对平板式筏基沉降问题的影响程度。绘制筏板的沉降曲线,通过观察沉降值变化规律,发现筏板板厚和筏板边缘外伸长度对基础沉降都有一定影响。

In this paper, the effects of the thickness and overhanging length of the plate-type to the settlement of plate-type raft foundation have been discussed brielfy. Models, which have different thickness and overhanging length of the plate-type, have been built to conduct FEM simulation analysis. The settlement curves obtained from the calculation of different models shows its changed regularity. The result indicates that the thickness and overhanging length of the slab have a certain inlfuence on the settlement of plate-type raft foundation.
