摘要

并行计算己成为求解大规模岩土工程问题的一种强大趋势。以水布娅大型洞室群软岩置换方案优化为例

探讨了方案优化中的并行计算问题，分析了并行计算中的编程模式、任务划分、负载平衡和编程方法等问题，在 W id n o w s 环境下的 PC 机群上成功实现了软岩置换方案优化的并行计算，并获得了近乎线性的加速比

从而大大提高了方案优化的计算速度和效率

为岩土工程计算并行化思路提供了重要参考。

Abstract

Parallel computing is becoming the strong trend of solving large scale geotechnical problems。Taking the scheme optimization of the soft-rock replacement in Shuibuya large cavern group for example

parallel computing for the scheme of optimization is discussed。 The following problems such as the parallel programming modes

programming method， tasks dividing data communication and load equilibrium are analyzed。The parallel computing for the scheme optimization of soft-rock replacement is successfully accomplished in the personal computers which run in the windows operating system。The final results indicate that the linear speedup ratio is almost achieved

accordingly the computing speed and efficiency of the scheme optimization is promoted greatly。This paper provides an important reference for the application of parallel computing in the geotechnical engineering.
