巴家嘴水库泥沙淤积现状分析及清淤措施

Analysis of Current Sediment Deposition in Bajiazui Reservoir and its Dredging Measures

针对巴家嘴水库淤积问题,通过对水库淤积现状及成因进行分析,在水库减淤措施可行性分析的基础上,将3种清淤方法进行对比分析,并在分析泥沙淤积物起动条件的基础上,提出了基流排沙和高渠泄水冲刷相结合的水库清淤措施,可缓解水库淤积问题,恢复水库有效库容,延长其使用寿命。

Aiming at the sediment deposition of Bajiazui Reservoir,by analyzing the current sediment deposition and causes of sedimentation in the reservoir,and on the basis of the feasibility analysis of the measures to reduce sedimentation in the reservoir,the three dredging measures are compared and analyzed,and on the basis of analyzing the starting conditions of sediment deposition,the base flow drainage method combined with high canal discharge and scouring is proposed which can alleviate the problem of reservoir siltation,restore the effective storage capacity of the reservoir,and prolong its service life.
