| 中文摘要: |
| 了使用潘家铮算法对滑坡水平运动模式和垂直运动模式下初始涌浪高度进行求解的基础上，基于线性插值原理，提出了滑坡斜向运动模式下的初始涌浪高度的计算公式。以长江的新滩滑坡为例，根据修正后的算法对其初始涌浪高度进行了计算，并利用计算结果采用潘家铮方法对涌浪的传播及爬坡高度进行了分析计算。结果表明计算的初始涌浪高度值及经传播后的爬坡高度与实际调查值比较吻合。 |
| 英文摘要: |
| Based on the methods for calculating the initial surge heights due to horizontal and vertical movement of slide suggested by Pan, an improved formula for slide movement with arbitrary incline angle is proposed by applying the linear interpolation approach. The formula is used to calculate the initial surge height occurred to the Xintan Slide, located at the Yangtze River. It is found that the calculated climb up height of the surge in the process of propagation is in good agreement with field investigation data. |
