1964年以来,我们开展了水库长期使用问题研究。为了了解长期使用水库冲淤过程的内在规律,本文主要对水库的淤积发展过程,平衡时纵横剖面的形态及平衡后的冲淤特性等问题进行研究,供工程规划和调度参考。一、水库淤积相对平衡水库淤积最终将导致淤积的终止,而进入相对平衡.水库淤积平衡按河床形态,可分为纵向平衡(纵剖面达到平衡)与横向平衡(横剖面达到平衡);按泥沙输移,可分为悬移质
Since 1964, we have conducted a study on the long-term use of reservoirs. In order to understand the inherent laws of long-term reservoir scouring and silting, this paper mainly studies the siltation and development process of reservoirs, the aspect forms of vertical and horizontal sections and the scour-silting characteristics after the balance, and other issues for project planning and scheduling reference. First, the relative balance of reservoir siltation Reservoir siltation will eventually lead to the termination of siltation, and into the relative balance. Reservoir siltation balance according to riverbed morphology, can be divided into vertical balance (vertical profile to achieve balance) and horizontal balance (cross-section to achieve balance); mud Sand transport can be divided into suspended matter
