侧裂面是控制拱坝抗滑稳定的重要力学边界之一 ,可能构成侧裂面的陡倾结构面称为侧裂结构面 .如果侧裂结构面为随机基体裂隙 ,那么其迹长估计就是侧裂面边界条件分析中的一项重要内容 .作者在分析H -H、Laslett和 2L0 5三种迹长估计方法的基础上 ,综合确定模型方法和概率模型方法 ,提出了一种适用于侧裂结构面迹长估计的新方法———广义H H迹长估计算法 .并利用此方法对西南某大型水电站工程侧裂结构面迹长进行了研究 ,证明了该方法的正确性
Side cracks are one of the important mechanical boundaries that control the anti-sliding stability of arch dam. The steeply-tilted surface that may constitute the side-crack is called the side-cracked structure. If the side-cracked structure is randomized, then the trace is estimated On the basis of analyzing the three kinds of track length estimation methods of H-H, Laslett and 2L0 5, the authors synthetically determine the model method and the probabilistic model method, and propose a method that is suitable for the lateral A New Method for Estimating the Length of Cracks in Surface Structures - Generalized HH Trace Estimation Algorithm. By using this method, the trace length of the lateral crack structures in a large hydropower station in Southwest China has been studied, and the correctness of the method has been proved
