南宁地区软岩嵌岩桩的有限元计算机模拟

FEM COMPUTER IMITATION OF ROCK-SOCKETED PILES IN WEAK ROCK OF NANNING

以南宁软质岩中的嵌岩桩为研究对象,借助有限元ANSYS软件的结构静力分析功能,进行了嵌岩桩的有限元计算机模拟试验。探讨了桩的长径比、嵌岩深度对嵌岩桩的荷载传递性状的影响。模拟计算结果与已有研究比较表明,用ANSYS软件模拟嵌岩桩的荷载传递性状是可行的。

Taking the rock-socketed piles in weak rock in Nanning as the imitated subject, with the help of ANSYS which is a finite element software, the computer analogue test of rock-socketde piles is done. The paper also investigates the effect of rock-socketed depth, length-diameter ratio on the behavior of load transfer of rock-socketed piles. The comparisons of the results of imitation with the existing research results show that using the ANSYS to imitate the load transfer of rock-socketed piles is feasible.
