蔡庄水库由于输水洞泄量小，库区地形复杂，流域内水土流失严重和水沙调节不当等原因，水库从１９６０年拦洪蓄水运用到１９８９年，水库淤积１２６０万ｍ３，淤积占总库容２０７０万ｍ３的６１．８７％。本文介绍了水库的淤积现状，建立了水沙数学模型，分析了水库的水沙特征和水库淤积的主要因素，在此基础上提出了水库减淤要求的泄流排沙建筑物规模和合理的水沙调度运用方式，以及加快流域内的水土保持治理等对策，为水库的改造和合理运用提供了决策依据。
Due to the small discharge of water diversion tunnel, complex terrain in the reservoir area, serious water and soil loss in the basin and improper regulation of water and sediment, the reservoir of Chuangzhuang Reservoir has been used from 1989 to 1999, with reservoir deposition of 12.6 million m3, The total storage capacity of 20.7 million m3 61.87%. This paper introduces the present situation of reservoir silting, establishes the mathematical model of water and sediment, analyzes the characteristics of water and sediment of reservoirs and the main factors of reservoir siltation, and on the basis of this, puts forward the scale and reasonable The methods of water and sediment regulation and the countermeasures such as speeding up soil and water conservation within the basin provide decision-making basis for the reconstruction and rational utilization of reservoirs.
