输水管道设计与施工中的几个问题

Several Problems in Design and Construction of Water Conveyance Pipe

输水管道(尤其是大口径混凝土管道)工程的设计与施工技术,目前已日渐成熟,但也存在着如管径选择、管床形式、土方回填等方面容易忽视的一些问题,而且在有些工程中已成为影响质量的主要因素。

Absrtact:Although the design and construction technique in water conveyance pipe,especially for the large-diameter concrete pipe,have gradually reached maturity at present time,yet still there exist some problems which are liable to be neglected such as the problems in selecting the pipe-diameter,in selecting the socle type and in back-filling earth. These Problems have furthermore become main factors influeneing the construction quality now at some projects.In this paper,these problems stated above are described.
