| 摘 要： | 对于有埋深无体积质量黏性土地基极限承载力的求解,目前大多数土力学的书籍中都是先假定滑移面然后用静力平衡的方法求解,这样的求解过程是不精确的.利用Coulomb-Mohr屈服准则,基于R.希尔调和挤出图,采用了塑性力学滑移线的方法求解,得到了相同的结论,但是推导过程却大为简化.

| Abstract: | A direct solution of ultimate bearing capacity of null-gravity soil,which is based on the Coulomb-Mohr yield criteria,was derived by the method of the slip-line in plastic mechanics,contrast to the method of static equilibrium in most of the soil mechanics literatures.The result calculated by this method is equal to that by the method of Lu Pei-yan,but the deriving process is much simpler. |
