摘要
针对参数值选取直接影响数值模拟结果的准确性,结合燕山水库土石坝三维渗流有限元分析,采用正交试验设计及其统计分析方法,探讨了渗流参数对三维数值模拟结果的敏感程度、区分影响计算结果的主要参数和次要参数,并确定了渗流参数的最不利组合,使计算结果更符合实际。
The parameter value selection directly affects the accuracy of numerical simulation results. In this paper combined with three dimensional finite element analysis for seepage field in earth dam of Yanshan Reservoir, the author uses orthogonal experimental design and statistical analysis to study sensitivity of seepage parameters in three-dimensional numerical simulation. The main parameters and secondary parameters effecting the result of calculation are distinguished. The most unfavorable combination of seepage parameters is identified. This makes calculations more realistic
