摘要
采用模糊有限元分析了面板坝堆石材料的参数敏感度。其计算结果包含大量信息 ,与普通有限元相比 ,可更清楚地看到坝体位移随参数的变化规律。同时 ,提出了模糊有限元平衡方程的遗传算法解法。
Fuzzy finite element is employed for analyzing parameter sensitivity of rockfill dam. The results contain much useful information.In comparison with the common finite element,the laws of dam body displacement varying with parameters can be clearly seen. Also, a method based on genetic algorithm for solving the fuzzy finite element equilibrium equations is suggested in this paper. The research results are of great reference value for civil engineering experiments and engineering design of rockfill dam.
