摘要
本文根据国家“七五”重点科技攻关课题《16—2》中有关科研成果资料,从三峡工程水库工程地质条件出发,分析了川江航道的滩险情况,认为崩塌、滑坡是滩险形成的重要原因。三峡工程蓄水后,虽然对岸坡的稳定局部产生不利的影响,可能诱发新的崩塌、滑坡,但水库建成后,川江航道水面坡降减少、水面增宽、水深加大,对航道有利,这是主要的。由于三峡库容大,崩塌滑坡土石方量与库容比较是微不足道的。
In terms of the engineering geological conditions of Shanxia reservoir project,this paper analyses the dangerous conditions of the banks of Chuanjiang waterway,considering landfall and landslide to be the most dangerous.The water storage of Shanxia reservoir would probably affect the stability of slope so as to make landfall and landslide,but the conditions of Chuanjiang waterway would turn out to be favourable with the reduction of slope on the surface of the water.Compared with the reservoir capaci- ty of Shanxia project,the effects of landfall and landslide is trifling.
