AbstractTwo important aspects in displacement back analysis, calculation efficiency and reliability, are discussed. Firstly the error back-propagation neural network (BP network) is used to substitute the time-consuming finite element analysis, and secondly genetic algorithm is used for the optimization of objective function, making back-analyzed solutions irrelevant to initial values. The feasibility is verified by back analysis of a three-media slope. 探討了計算速度和可靠性這兩個在位移反分析工作中非常重要的問題。一方面用 BP網絡代替有限元計算提高了計算效率 ,另一方面用遺傳算法代替常規的優化算法 ,使反分析結果與初值無關。三介質邊坡算例驗證了上述解決方案的可行性。
