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。
To reduce the material amount of anti-slide retaining wall and decrease the expense on the premise of safety, a numerical model was established for the optimization of the anti-slide retaining wall and was solved with the pattern search method. In this model, the geometric parameters were regarded as variables and the minimal section area was regarded as the target function subjected to some constraints. An optimal design program was developed. The results of an example with this program proves that the cost of the anti-slide retaining wall can be largely decreased.
