库区滑坡失稳易引起堵江事件, 而堵江堰塞坝的高度则直接影响水库能否正常运营调度, 特别是对中小型水 库而言。综合前人对滑坡堵江的研究成果, 以西南山区某中型水库库区滑坡堆积体为研究对象, 假设滑坡失稳堵江 为完全堵江, 对滑坡堵江可能性进行预测, 着重选取三种方法对滑坡堵江的高度进行预测, 并讨论了滑坡堵江的负 效应, 从而完成对库区滑坡堵江的风险性预判。以此初步建立了针对山区中小型水库滑坡堵江预测的研究思路, 以 期为此类问题的分析提供参考。

[Abstract]
The natural landslide damming is much mor e likely to happen in the reserv oir ar ea, and the heig ht of landslide dams di2 rectly affects the normal o perat ion of r eser vo ir, especially for medium and small2sized r eser voirs. I n this paper , the author sum2 ma rized pr evio us r esear ch r esult s on landslide blo cking r iver and studied the landslide accumulatio n body in the reservo ir ar ea o f a medium2sized reserv oir in Southwest China o n the basis o f assume that it is blocking the r iver com pletely , predicting the possi2 bilit y of landslide damming of the r iver . Then the autho r par ticular ly selected thr ee methods to predict the height of the dam and discussed its negative effect s, so as to complet e the risk pr edict ion o f landslide damming of r iv er in reserv oir ar ea. On this ac2 co unt the autho r has pr elim ina rily built the basic research thinking for the prediction o f landslide damming o f r iver in medium and small2sized reserv oir of mo untaino us area, in or der to pro vide a cer tain refer ence for solv ing this kind of pro blem.
