| 摘 要： | 将Monte-Carlo随机方法与并行有限元方法结合，设计了基于PC机群的并行随机有限元算法，每一次随机模拟产生一个随机场，作为一个样本，代入有限元进行稳定性计算，发挥并行有限元计算量大、计算速度快的特点，克服了Monte-Carlo方法计算时间长的缺点。用C++语言结合MPI消息传递接口开发了相应的计算软件，计算了1 000个随机样本的边坡可靠度问题，验证了程序的可靠性及高效性。

| Abstract: | A parallel stochastic FEM based on PC cluster is designed by combining Monte-Carlo stochastic algorithm and domain decomposed finite element method. Making a random field as a sample, exerting the virtues of parallel FEM, huge computing capacity and fast computing, the long time consuming disadvantage of Monte-Carlo method is conquered. Developed parallel computing program using C++ and MPI, then the reliability of a slope is analyzed with 1 000 stochastic samples; and the robust and efficiency of this algorithm are validated. |
