摘　　要：以新疆某长距离输水工程为例,针对管道沿线穿越不同的地质条件、不同宽度洪沟,在工程管线设计洪水重现期内洪水的防护进行分析。通过分析交通、明渠、埋地管道等常见的线性工程防护型式,确定工程建筑物布设型式;再根据穿越的山前倾斜砾质平原区、低山丘陵区、山前剥蚀准平原区三个地貌单元,对防护关键参数进行定量化分析;最后结合洪沟洪痕确定防护范围,为长距离输水管道沿线洪沟处防护设计提供参考。Taking a long-distance water conveyance project in Xinjiang as an example,flood control during the design flood return period of pipelines for crossing different geological conditions and flood gullies with different widths along the pipeline were analyzed.First,the layout type of engineering buildings was determined by analyzing common linear engineering protection types such as transportation,open channels,and buried pipelines.Subsequently,quantitative analysis was conducted on the key protection parameters based on three geomorphic units:the inclined gravel plain area in front of the mountain,the low mountain and hilly area,and the eroded quasi plain area in front of the mountain.Finally,the protection range was determined based on the flood marks in the flood ditch.This engineering example can provide reference for the protection design of flood ditches along long-distance water conveyance lines.
