摘要
本文通过对工程实例分析,介绍了大口径大跨度拱形管道及倒虹管这两种输配水管线过河设计方案,经综合比较,认为在河床水文地质条件不利的情况下,采用大口径大跨度拱形管道更为安全、经济.
By means of engineering practice analysis two design schemes of river-- crossing water conduits in forms of big size arched culvert and inverted syphon tube are presented and estimated. It is shown that under river bed with unfavorable hydrogeolog-ic conditions using the big size arched culvert is safer and more economical.
