In the loose model test, we can not only consider the nonlinear of the earth and rock-fill deformation, but also realize the seepage.
在松散体模型试验中，不仅可以考虑土石变形的非线性，而且可以实现渗流，地震荷载亦可作为体积力处理。

In the loose model test, we can not only consider the nonlinear of the earth and rock-fill deformation, but also realize the seepage. The earthquake loadings can be thought as the body force.
