| 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要求为约束条件，得到非线性优化数学模型，并利用优秀国产数学软件1stopt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. |
