Abstract

Abstract: Considering the poor anti-filtration performance of the traditional sand filter under the bad geological conditions, a three-dimensional composite drainage mat was proposed and applied as a new drainage filtration structure, and its parameters including drainage, anti-filtration and durability were tested by indoor experiments. The effect, application condition and characteristics of the three-dimensional composite drainage mat were discussed based on its application in Huguang-Luohuzhou waterway regulation project in the middle reach of the Yangtze River, which provided experience and references for similar engineering projects.

Key words: channel engineering, three-dimensional composite drainage mat, Waterway regulation, Revetment engineering

摘要： 针对不良地质条件下传统砂石反滤结构反滤性能不足的问题，提出采用三维复合排水垫的新型排水反滤结构，并通过室内实验测定了其排水性、反滤性和耐久性等参数。结合长江中游湖广-罗湖洲河段航道整治工程应用实践，分析了三维复合排水垫的效果及应用条件和特点，可为同类工程提供经验借鉴。
