摘　　要：自2008年起,三峡工程由初期蓄水位156.0m运行转入正常蓄水位175m试验性运行。本文分析归纳了三峡工程175米试验性蓄水运行期的泥沙观测资料,从长江上游水文情势变化、水库实测泥沙淤积资料分析、坝区实测泥沙资料分析、大坝下游河道冲淤资料分析四个方面进行归纳,得出了相关结论。Since 2008,the Three Gorges Project Reservoir has been on a transition from the initial pool level of El 156.0 m to the normal pool level of El. 175 m for trial operation purpose. This paper analyzes the sediment observation data in the trial impounding period of the Three Gorges Project to pool level of El. 175-meter. Four aspects are analyzed including hydrological situation change in the upper reaches of the Yangtze River,the analysis of sedimentation data in the reservoir,the analysis of sediment data in the dam area,and the scouring and silting data of the downstream dam.
