| 摘 要： | 在满足安全要求的前提下,为了减少重力式抗滑挡墙的材料用量,降低工程造价,以抗滑挡墙的几何参数为优化变量,以截面面积为优化目标函数,在满足抗滑移、抗倾覆和地基承载力等约束条件的基础上,建立了重力式抗滑挡墙的优化模型,并用Hooke-Jeeves模式搜索算法求解,并编制了优化设计程序.通过对某抗滑挡墙的优化分析,结果表明:采用本文方法对重力式抗滑挡墙进行优化,在满足安全的条件下可以明显的降低工程费用,在滑坡治理工程中具有一定的实用价值.

| Abstract: | To reduce the material amo unt of ant i-slide retaining w all and decr ease the ex pense on the
pr emise o f safety , a numerical model w as establ ished for the optimizat ion of the ant i-slide retaining w all
and w as so lved with the pat tern search metho d. In this mo del, the geomet ric parameters w ere reg arded as
variables and the minimal sect ion area w as reg ar ded as the tar get funct ion subjected to some const raint s.
An o pt imal desig n progr am was developed. The r esult s of an ex ample w ith this pr ogr am pro ves that the
