摘要

。本文对环形筏和圆形筏进行了有限元分析。选择不同的内半径与外半径比,考察了几何特性对环形筏的影响。环梁半径与筏板外半径之比也发生了变化。采用有限元法确定了环形筏和圆形筏的临界力矩和挠度。对环形筏板和圆形筏板的临界力矩和挠度进行了比较,以便选择合适的筏板基础类型。利用ANSYS软件对两种结构进行了有限元分析。结果表明:与圆筏相比,环形筏的临界力矩和挠度值较小;不同的内半径与外半径之比和环梁半径与筏板半径之比影响临界力矩和挠度。

Analysis Of Annular Raft Foundation using Finite Element Method
. A finite element analysis of an annular raft and a circular raft is undertaken in this work. Different ratios of inner radius to outer radius are chosen to examine the effect of geometrical characteristics of annular rafts. The ratio of radius of ring beam to outer radius of raft was also varied. Finite element method is adopted to determine critical moments and deflections in both annular and circular rafts. Comparison of these critical moments and deflections is made for both annular raft and circular raft,for selection of suitable type of raft foundation. Finite element analysis of both the rafts is carried out using ANSYS software.The results show that values of critical moments and deflections in annular raft are less in comparison with those values in circular raft. Different ratios of inner radius to outer radius and radius of ring beam to radius of raft effect critical moments and deflections.
