摘要
系统地介绍了结构塑性极限分析的原理和方法。借助有限单元法和线性规划,运用塑性极限分析的下限法,可求解岩土边坡的极限承载力和安全系数。算例表明了该方法的正确性并具有较高的精度,同时,分析了该方法的困难所在。
The theory and method of the plastic limit analysis were introduced systematically; by using the finite element methods and linear programming, the lower limit method can evaluate the bearing capacity and the safety factor of the rock-soil slope. The example shows the correctness and the high precision of this method; meanwhile, its difficulty has been analyzed.
