摘　　要：向家坝水库蓄水运行之后,其下游河道的水沙环境、河床形态将发生很大的变化,本文以距离向家坝坝址较近的典型浅险碍航为主的马皮包河段为研究对象,分析了向家坝运行之后的来水来沙条件、河道演变规律、通航影响及设计水位的变化情况、航道建设及通航利用方式等问题,以期为今后本河段航道维护和建设提供参考。After the impoundment and operation of Xiangjiaba Hydropower station, the water-sediment environment and river-bed topography of its lower river reach are to be greatly changed. Therefore, by taking the main typical dangerous shoal of navigation obstruction Mapibao Shoal near the site of the dam for the hydropower station as the study object, the conditions of incoming water and sediment, evolution law of river channel, impacts on navigation, change of the design water level, water-way construc- tion, utilization mode of navigation, etc. after the operation of the hydropower station are studied herein, so as to provide some references for construction and maintenance of the water-way of the river reach.
