Based on the above, the evolvement rules and the anomalism mining methods of crossfeed between dam body and foundation are presented. 为使上述理论应用于实际工程,本文建立了坝体与坝基互馈的预警系统。
Mechanical Behavior and Analysis Theories of Crossfeed between High Dam Body and Complex Foundation 高坝坝体与复杂坝基互馈的力学行为及其分析理论
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. representative strain of the crossfeed surface. 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。
Behavior and decision method of crossfeed surface between concrete dam body and foundation 混凝土坝与坝基互馈面及其确定
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. 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。
