水利水电工程沉沙池的运行设计和原型观测

沉沙池作为多沙河流引水枢纽的重要建筑物,其正常运行是发挥枢纽工程效益的重要条件。沉沙池设计应根据河流泥沙情况及枢纽运行条件,提出合理的运行设计和原型观测设计。运行设计应满足沉沙池运行水位、设计入池流量、含沙量、泥沙沉降设计标准和运用时间等运用条件。原型观测设计要有针对性,根据工程等级、规模、类型、布置、水沙条件等,确定相应原型观测内容和观测布置。

Talking about Operation Design and Prototype Observation of Desilting Basin of Water Conservancy and Hydropower Projects

The normal operation of desilting basin, being an important building in diversion pivot of the sediment-laden river, is an important condition of developing the engineering benefit of the pivot. For the design of desilting basin, the reasonable operation and prototype observation design should be offered according to the river sediment situation and pivot operation condition. The operation design must meet with its operation conditions of the operation level, design inflow discharge, sediment concentration, sediment settlement design standard and the operation time. The prototype observation of the desilting basin must be designed according to the conditions of the engineering degree, scale, type, layout and water-sand condition,etc.
