目前土坝的稳定分析方法已比较成熟,有瑞典法,简化毕肖普法,改良瑞典法,摩根斯屯-普莱斯法和杨布法等,并具有相应的程序。但在寻找安全系数极值方面需进一步完善。近年来随着优化理论的应用,寻找最危险滑裂面的位置可以表示为无约束优化问题,用无约束优化方法求解。本文介绍采用单纯形优化法寻找最危险滑弧位置的程序设计过程,程序中对计算滑弧稳定的方法不做更多的研究,只采用现在工程上常用的瑞典法,并编写在相应的子程序中。对于需
At present, the method of stability analysis of earth dam is relatively mature. There are Swedish method, simplified Bishop method, modified Swedish method, Morgenstern-Price method and Yang Bufa method, and have corresponding procedures. However, it is necessary to further improve the search for the extreme value of safety factor. In recent years, with the application of optimization theory, finding the most dangerous slip surface can be expressed as an unconstrained optimization problem, which is solved by the unconstrained optimization method. This article describes the use of simplex optimization method to find the most dangerous position of the arc slip programming process in the calculation of the method to calculate the stability of the arc slip do more research, only the Swedish method commonly used in engineering, and prepared in the corresponding sub Program. For the need
