| 摘 要： | 面板堆石坝的三维非线性有限元分析，对并行计算提出了较高的要求. 在建模阶段挖掘出模型内在的并行性，由相邻坝段构成子结构，既方便灵活又能满足区域分解法的要求. 编制了适用于机群的并行多波前法计算程序，并应用于西龙池下库沥青混凝土面板堆石坝的有限元数值分析，其计算结果和串行完全相同，通过对加速比和并行效率进行分析，结果表明采用并行多波前法求解面板堆石坝的三维非线性有限元问题有效且算法简单，易于实现，无需辅助的任务分配程序.

| Abstract: | Parallel computations are needed for effectively analyzingthe concrete-faced rockfill dam using 3D nonlinear finite element method.Parallelism is to be found during modeling stage and some neighbouringdam sections are made into a substructure. It is convenient and cansatisfy the demands of the domain decomposition.A parallel multi-frontal code for COW isdeveloped and applied to the numerical analysis of Xilongchi lower reservoirdam, an asphalt concrete faced rockfill dam, with the same result as in aserial calculation. From the speedup ratios and parallel efficiency, itis shown that the parallel multi-frontal method can be used toreliably analyze the concrete-faced rockfill dam and itis simple and easy to realize, without requiring an accessorial task assignmentsubroutine. |
