Rockfill is elastoplastic itself and its stress-strain relationship is nonlinear. So the calculation method must be incremental FEM.
堆石体本身为弹塑性结构，应力和变形呈非线性关系，故确定计算方法采用增量有限元法；
The method was based on the conception that incremental relief of in-situ stress generated incremental displacement on the cutting face. A release force was employed to realize the idea.
