| 摘 要： | 在利用可靠度理论建立功能函数的基础上,对功能函数的求解进行了一次二阶矩两种方法的比较与分析,并对边坡的可靠指标进行了验算.结果显示,用改进一次二阶矩法将线性展开点(可用反算法求得)选在极限平衡状态面上,可减小计算误差. |

| Abstract: | On the basis of building power function by the reliability theory,comparison and analysis of the two methods of LOSM(linear second order moment)are made on the solution to the power function,and check calculation is carried out on the slope reliability index.The results reveal that calculation errors can be reduced with the linear expending nodes,which can be found out by anti-inference method,decided on the limiting equilibration surface based on the advance LOSM method. |
| Keywords: | linear second order moment slope stability reliability index |
