河流和渠道中的控冰结构运用现状评述

Developments of Ice Control Structures in Rivers and Canals

我国冬季寒冷地区的河流渠道都会面临流冰问题,控制流冰,减轻冰害意义重大。该文以流冰的结构控制方法为出发点,从结构形式、基本原理、主要优缺点及在运用过程中存在的限制等方面对国内外现存控冰结构形式作了分类评述,以期拓宽我国冰控制技术的发展思路,并为工程中选用最优结构形式提供借鉴。

Rivers and canals in cold regions face the ice flowing problem in every winter, and it is of great sense to control ice flowing and mitigate ice jam. From the aspects of the various structure forms, mechanisms, limitations, main merits and drawbacks, different kinds of ice control structures are reviewed respectively used in China and other countries at present. The analysis and summary will be helpful to develop ice mitigation technology, and provide the reference to select the optimal structure form in the engineering practice.
