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。

Cable reel motor torque constant tension which has the characteristics When the load increases in the motor output shaft speed will automatically come down, volume Rao assured when cable tension unchanged. Rao nature of this excellent performance closely integrated with the Volume; Cage used motor hysteresis coupling increases in size, functionality, easy installation, the constant tension similar characteristics, we can under the conditions required output torque. They can pull the cable external circumstances, hysteresis coupling protect cables; using torque motor controller to increase frequency hysteresis couplings Surge part because of the cable reel SCR converter using a new technology operation, smoothing adjustments to the motor terminal voltage, thereby ensuring that the output torque of the motor unchanged. so that the cable can smooth the road with the truck

其中力矩电机电缆卷筒具有恒张力的特点，当负载增加时电机的输出轴转速能自动随之降低，保证电缆卷饶时张力不变，这个优越的性能与卷饶性紧密结合；采用笼型电机加磁滞式联轴器具有体积小，功能全，安装维护方便，近似恒张力等特点，既可以根据工况需要输出力矩，又可以在电缆受外力拉住的情况下，通过磁滞式联轴器保护电缆；而采用力矩控制器加变频电机加磁滞式联轴节的电缆卷筒因其调压部分采用可控硅变流新技术，可以平滑地对电机的端电压进行调节，从而保证了力矩随负载的变化而改变，使电缆能平稳的跟大车的行进。
