摘要
万安水库建成后，由于水库改变了坝下游来水、来沙条件，对下游河床产生冲刷．本文根据１９８９年～１９９４年的观测资料，着重分析水库运行５年来对坝下游的河床冲刷，阐述河床冲刷过程对坝下游水力因素的变化及防洪、航运的影响。
After Wanan Reservoir was built,the down stream bed was washed outbecause the reservoir changed the water and sand condition of the dam downstre-am According to the 1989～1994 observational data,this paper analyzed the st-team bed erosion of thie dam dowt strcatn after the reservoir has been operated for five years and stated the effect of the dam downstrearn hvdraulic factor va-ritation, flood protection, shipping because the stream bed was washed out.
