| 摘 要： | 在边坡算例的基础上,分别应用有限元强度折减法和有限元重度加大法进行安全系数的计算,并将计算结果与极限平衡法结果相对比.结果显示:有限元重度加大法的结果要大于有限元强度折减法计算的结果.边坡高度较矮时,二者的结果相差比较大;当坡度较大,边坡高度较大时二者计算结果基本相同.边坡坡度大于等于1∶1.5时,可以采用重度加大法方...

| Abstract: | Based on the calculation examples of slope safety factor,the finite element strength reduction method and finite element gravity increasing method are used for the calculation of slope safety factor,and the calculation results are contrasted with the result from the limit equilibrium method.The results show that the result from the gravity increasing method is higher than the result from the strength reduction method.When slope is lower,the difference between two results is larger;otherwise the difference i... |
