Conceiving and Analyzing the Sediment Removal Scheme for the Caizhuang Reservoir

分析了水库的淤积现状,指出由于淤积严重当前水库的水量不能满足供水需求,论证了水库清淤的必要性。在此基础上,采用径流调节时历法计算出在供水保证率不小于95%的情况下较为合理的兴利库容和供水能力,提出了水库清淤的构想,初步论证了清淤方案的合理性。

In this paper, the present deposition situation of the Caizhuang Reservoir is analyzed.It is indicated that due to severe deposition,the present water supply volume of this reservoir can＇t meet the demand of water users. The necessity of the sediment removal from this reservoir is demonstrated. On the basis of above-mentioned analysis, by using the chronological series method for runoff regulation, the more reasonabie volume of beneficial reservoir capacity and the value of water supply capacity are computed, which are obtained under the condition that the ensurance probability of water supply is not less than 95%.Subsequently the conceiving of sediment removal are put forward and the resonableness of this sediment removal scheme is oreliminarilv discussed.
