对于多个互馈优势面，采用极限平衡理论计算各个面的抗滑稳定安全系数，定义安全系数最小的面为互馈面。
For the more than one crossfeed dominant surfaces, the one whose safety index is least is defined as the crossfeed surface based on limit equilibrium theory.
并基于突变性判据，利用互馈面实际接触面积或分形维数曲线随名义应变变化的特征，得到了坝体与坝基互馈的转异判据。
With the help of catastrophe criterion, the anomalism criterions of the crossfeed between dam body and foundation are acquired from the real contact area or fractal dimension curve vs.
