前言 进行排沙设施的设计,首先要解决工程是否需设置排沙设施?其规模应该是多大?这是多沙河流枢纽设计中最关心的问题。本文拟通过对工程实际泄量的复核及近几年来各工程排沙资料,结合水库泥沙淤积规律的分析研究,回答上面提出的问题。 一、排沙泄流规模问题的提出 建国以来,各地兴建了大量的水利水电工程,对于泥沙带来的危害,经过多年来的探索认为可以通过排沙方式予以减轻,而在枢纽的总泄量中应该留出多少泄量作为控制泥沙的
Foreword The design of sediment discharge facilities, we must first solve the project need to set up sediment discharge facilities? Its size should be much? This is the most concerned about the design of the Dousha River hub design issues. This paper intends to review the problems raised above by reviewing the actual discharge of the project and the sediment discharge data of various projects in recent years, combining with the analysis and research of the sedimentation rules of reservoirs. First, the issue of the size of sand discharge Since the founding of the PRC, the construction of a large number of water conservancy and hydropower projects around the hazards of sediment, after years of exploration that can be reduced by means of sand discharge, and the total vent in the hub How much should be set aside to control the amount of sediment discharge
