摘要：随着城市生态建设的趋势，河道拦水坝的应用需求越来越大，不仅要满足航运、灌溉、行洪等常规功能，还要满足与 环境协调、生态水景的要求。由于橡胶坝坝袋易破损、易老化、无法快速截洪泄流、景观融合度低等缺点，新型钢构拦水坝应运而生。本文介绍了5种新型 钢构拦水坝即升卧式闸门、气动盾形闸、钢坝闸、液压升降坝及合页活动坝，阐述了其工作原理及结构特征，对比分析了其地基要求、土建工程量及安装难度、运行使用、景观生态特点和造价，归纳总结了各自的适用条件，为水利工程钢构拦水坝的应用选择提供参考。

Abstract: As constructions of Ecological City, the demand of river dam increases fast not only to facilitate general functions such as shipping, irrigation, flood discharge, but also to provide harmonious with environment, ecological waterscape. Steel Structure Dam emerges as rubber dam exposes its vulnerable and aging of bags, slow response to discharge flood, and poor landscape effect etc.. This paper briefs origins and development in engineering application of 5 new steel structure dam. Including: Horizontal sluice gate, Pneumatic shield Dam, Hydraulic rotating dam, Hydraulic lifting dam, Hydraulic Elevator Dam, furthermore it explains how these dam works and its structure characteristics. Finally, through comparison of foundation requirement, civil works quantity, installation difference, operation, ecological waterscape, shortcomings and cost analysis，this paper summarizes and analyzes the applicable and inapplicable channel conditions for aforesaid five new steel structure dam and provides reference for application of steel structure dam.
