摘要
设计沉沙池时,首先要解决的问题之一是悬移质泥沙沉降计算方法。为此,对目前国内外业界采用的计算方法分类进行分析,并以成都勘测设计研究院进行沉沙池原型观测的资料和成都勘测设计研究院科学研究所进行的专题水槽试验成果,对准静水沉降法、沉降概率法和超饱和输沙法三种方法进行了检验,其中超饱和输沙法偏差最小。为此,明确推荐采用超饱和输沙法。该方法已经列入《水利水电工程沉沙池设计规范》。
In the design of sand basin, the first problem is to select the calculation method of suspended silt deposition rate. For this reason, we classify and analyze the calculation methods at home and abroad and check the following three methods: the apparent hydrostatic deposition calculation method, the deposit probability method and the supersaturated sediment transport method on the basis of test results from the Chengdu Hydroelectric Investigation and Design Institute. It is concluded that the least deviation is from the supersaturated sediment transport calculation method. Therefore this paper suggests that the supersaturated sediment transport calculation method should be adopted. And such method has been listed into the Specifications on the Design of Sand Basin of Hydropower and Water Conservancy Projects.
