应器为例的仿真结果也验证了控制器具有良好的控制特性。

A modefied egg function has been proposed and used in a bounding surface model. This model has potential value of applicaton since it reflects better actual situation of soil mass under loading. That is: when a stress point is still within the yield surface, the unrccovered plastic deformation would occur as stresses change, and using closed smooth function makes stress modification in the FEM much easier.

文中提出了一个改进蛋形函数，并采用这个函数建立了边界面模型，该模型由于机理上更好地反映了土体受荷时的实际情况，即当应力点在屈服面内时，随着应力状态的改变，仍然可以产生不可恢复的塑性变形，而在计算功能上由于使用了封闭光滑的边界面，不存在角点问题使有限元程序计算显得很方便，从这两个方面看，该模型具有潜在的应用价值。
