摘　　要：简要回顾了近年来关于河道立堵截流难度的研究进程,分析了截流难度的本质、控制因素及其后果,提出了截流难度衡量指标及其计算方法。分析了用该指标进行立堵截流难度判断与截流方案选择的可行性,并结合具体工程实例进行了计算。结果表明,采用抛投比率E衡量截流难度行之有效,可供立堵截流及其他截流难度衡量借鉴。At first, this paper makes a brief review on the research of difficulty by end-dumping in river closure during recent years. Then it analyzes the nature, control factors and consequences of the closure difficulty. A new index, with the name of dumping ratio, which measures the end-dumping difficulty in river closure, has been put forward along with the way to calculate, and the feasibility of it is analyzed at the same time. Also some calculated examples are supplied.

关 键 词：立堵截流 截流难度 截流方案 衡量指标 抛投比率
