由于水库蓄水水位的变化，库区时常发生山体滑坡，滑坡涌浪作用于锚泊船舶时可能会使船舶的锚链拉断，造成较大灾害。为研究滑坡涌浪传播特性和降低涌浪对船舶造成的损害，通过岩体滑坡涌浪概化模型试验，并基于多元线性回归分析方法，得到了首浪高度、涌浪高度衰减系数和最大锚链拉力的经验公式，进而推导出静水中船舶安全锚泊限制范围的计算公式。上述公式的确定，可为制定滑坡地点附近锚泊船舶的安全避险措施和预测滑坡涌浪产生的破坏范围提供依据。

Landslides occur frequently in reservoir area because of the fluctuation of impounded level. The ship anchor chains may be broken when the landslide generated waves act on the anchored ships, which may lead to greater disasters. To study the propagation characteristics of the landslide generated waves and reduce its damage on the ships, a physical model to simulate the waves generated by rock landslide is designed. The empirical formulas of the primary wave height, the attenuation coefficient of wave height and the maximum tension of anchor chains are obtained by using the multiple linear regression method;and then the calculation formula of the safe anchorage scope of the ships under hydrostatic condition is deduced. The above formulas provide an important basis for setting out the risk-controlling measures for the ships near landslide sites and predicting the damage range of landslide generated waves.
