摘要:
对于加筋土挡墙,以筋材总长度最小为控制目标,不发生任何模式的破坏为约束条件,建立非线性约束规划的优化设计数学模型.利用Matlab语言优化工具箱里的功能函数求解该模型,对一个加筋土挡墙进行优化设计.对于两种筋材型号的优化方案,采用强度较高的筋材方案能节省筋材用量的14%.实例的优化设计表明,加筋土挡墙外部稳定(挡墙抗倾和抗滑)的安全系数远高于设计值,起控制作用的是挡墙内部稳定(筋材抗拉和抗拔)问题.
Abstract:
An mathematical model of nonlinear constrain programming by taking the length of geotextile as an objective function and taking no destruction as the constrain condition,is established for the optimal design of reinforced retaining wall.The function in Matlab toolbox of optimization is used to solve the model.The optimal design for a reinforced retaining wall is conducted.The comparison between two optimal designs with two types of geotextile respectively,shows: the volume of the geotextile with higher strength is 14% less than the one with ordinary strength; and the safety factor of external stability of reinforced retaining wall is much higher than the design value,so the control condition is its internal stability.
