1 前言黄河下游河道整治工程多年来一直采用柳石搂厢进占、柳石枕护根、外抛散石护坡的结构型式,这种结构虽然具有施工简单、技术难度低、可就地取材等优点,但抗洪御险能力差,遇洪水易出险。为适应黄河下游防洪治理和经济发展的需要,邙金局积极探索新材料、新工艺、新结构坝型,选定抽沙充填土工织物反滤布长管袋褥垫筑坝新技术,以解决黄河传统筑
1 Preface The river course improvement project in the lower Yellow River has been using the structure of LiuShi huanxiang and LiuShiZhu to protect the root and throw the bulk rock slope for many years. Although this kind of structure has the advantages of simple construction, low technical difficulty, However, flood control ability is poor, in case of flood prone. In order to meet the needs of flood control and economic development of the lower Yellow River, Gold Bureau actively explored new materials, new processes and new structural dam types, and selected new technology to fill sand-filled geotextile filter cloth with long tube bag mat to solve Yellow River traditional building
