| 摘 要： | 软土路基沉降预测数值分析所需输入土体参数难以确定,是阻碍工程数值分析方法实际应用的主要原因之一。针对此,笔者研究了以现场量测位移为基础的位移反分析原理,提出了基于PSO-LSSM的位移反分析法,并以某工程为实例进行了演算,结果表明,所采用的PSO-LSSVM的反演分析方法在工程上应用是可行的。

| Abstract: | The soil parameters,which are input for engineering numerical calculation of softsoil roadbed settlement forcast,are uneasily determined.it is one of reasons to block numerical calculation in use.So,the writers studied the principle of displacement inverse analysis,put forward displacement inverse analysis with help of PSO-LSSVM,Through calculation and analysis foe example,it states feasible mothed that the inverse calculation analysis with help of PSO-LSSVM is in use. |
