利用1stOpt软件优化设计重力式挡土墙断面
摘要:为解决挡土墙设计指标计算较为繁琐,并且难以得出最佳结果的问题,以重力式档土墙的截面面积最小为目标函数,并以满足稳定性及地基承载力验算求为约束条件,得到非线性优化数学模型,并利用优秀国产数学软件lstopt优化求解。该方法避免了繁琐的试算过程,能得到经济合理的截面尺寸,并已成功应用在忠—武输气管线沿途水工保护工程中。
Abstract:In order to solve the complicated calculating indexes and difficulty to draw the best results of the retaining walls design. The smallest cross-section objective function of the gravity retaining wall is established which can meet the stability and the requirements of the bearing capacity of foundation, get the non-linear mathematical optimization model and a domes-tic mathematical optimization software lstOpt is used to solve. This method avoids the cumbersome process of the trial calculation and a reasonable cross-section of economic size could get, and has been successfully used in Zhong Wu gas line along the protection of hydraulic engineering.
