摘要
建立了以基坑支挡结构计算分析中的“ｍ”法为基础的位移反分析模型，给出了一种优化算法并讨论了解的收敛性和计算时间等问题，最后给出了位移反分析技术在基坑工程中的应用实例，说明所建立的模型及其算法是合理可行的。
One model of back analysis from displacement of the flexible retaining wall based on M method commonly used in the analysis of deep excavation is presented.An optimization method is given and its convergence and calculated time are discussed.A practical excavation engineering with observed datum in Shanghai is analyzed by the model and method,which proves that they are feasible for the excavation engineering.
