| 摘 要： | 采用有限元强度“折减”的基本原理，给出了地基承载力确定的数值模拟方法，并讨论了剪胀性材料的地基承载力与材料剪胀角的变化关系。算例表明，地基承载力随剪胀角的增大而增大。因此，求解地基承载力时，需要考虑剪胀角的影响。

| Abstract: | The numerical simulation method for the ultimate bearing capacity of ground is presented by adopting the theory of finite element strength reduction; and the significance in bearing capacity of the ground of the dilatancy angle of the material for the ground is discussed. An example is given; and its results show that the ultimate bearing capacity of ground is increased with the increasing of dilatancy angle; therefore, it’s of great need of considering the dilatancy angle of the ground material, when the ultimate bearing capacity of the ground is accounted. |

| Keywords: | dilatancy hearing capacity of ground strength reduction dilatancy angle |
