针对黄河中游地区数以万计的中小型水库和淤地坝普遍存在的设计标准偏低、工程不配套等问题,近年来提出了一种保坝护坝的新方案——坝面防护过水。本文阐述土坝过水方案在黄河中游地区保坝护坝中的作用和意义,必要性和现实可行性,以及此项工作目前的现状和需要进一步研究解决的问题。 In view of the problems such as the low design standards of the small and medium-sized reservoirs and silt dam in the middle reaches of the Yellow River and the lack of supporting projects, a new scheme of protecting the barrage is proposed in recent years - . This paper describes the role and significance, necessity and realistic feasibility of the earth dam over-water program in dam dams in the middle reaches of the Yellow River, as well as the current status of the work and the issues that need to be further studied and solved.
