某水库输水工程线路管材及管径比选分析

Analysis of Pipeline Material and Diameter Ratio of a Water Conveyance Project in a Reservoir

针对山区输水工程设计,因受地形起伏大、跨越冲沟河流、穿越重要交通道路等特点影响,导致输水工程部分的投资占总投资的比例往往较大,因此对管材和管径的选择尤为慎重。文章以某中型水库输水工程为例,在技术可行、安全可靠前提下,主要探讨输水工程中管材的选取和管径的确定,以期能为后续相关工程的设计提供借鉴。

For the design of water conveyance projects in mountainous areas, the proportion of investment in the part of water conveyance projects is often large because of the undulating topography, the crossing of gullies and rivers, and the crossing of important traffic roads, etc.. Therefore, the choice of pipe and pipe diameter is particularly careful. Taking a medium-sized reservoir water conveyance project as an example, the selection of pipe material and the determination of pipe diameter in the water conveyance project under the premise of technical feasibility, safety and reliability are discussed in this paper, in order to provide reference for the design of subsequent related projects.
