危岩体崩滑对航道影响及滑坡涌浪特性研究

本文通过分析峡各型通航河流危岩体崩滑产生的动态破坏和静态破坏,论述了滑坡对航道、水工建筑物及航行船只的危害,定量地估算了长江三峡链子崖崩滑对航道的影响,论证了峡谷型通航河流滑坡涌浪的主要特征,提出了涌浪估箅的经验公式,可供同类型地区进行估算滑坡危害时参考。

The Effect of Rockfall on Channel and the Study on the Characteristics of Surge Generated by Landslide

By analysing the dynamic and static destruction produced by the rockfall on navigable river in gorge, this paper expounds the harm of the landslide to channel, the hydraulic structure and the navigating ships. The effect of the rockfall on channel at the lian Zi Ya in the Three Gorses of the Yanstze River is quantitatively estimated. Forthermore, the main characteristics of the surges generated by landslide in gorge type navigable river are proved. Finally, the empirical formula to estimate the surges is proposed for estimating the harm of the landslide in the same of regions.
