当前,我国输气管道建设日益增多,同时水害问题对管道的威胁也愈加严重,不仅水体本身对管道有侵蚀的危害,其引起的滑坡、泥石流更是严重威胁着管道的安全运行。因此,需要对长输管道采取水工保护措施。通过调查可以看出,在长输管道工程建设之时,对管道沿线的山地、河道等都会在一定程度上造成较为严重的扰动,具体表现为使得原水土保持功能降低,使得水土流失的速度加剧,这样就会不可避免对管道周边的地域造成很大的 At present, the construction of gas pipelines in our country is increasing day by day. At the same time, the threat of water hazards to pipelines is also more and more serious. Not only the water body itself is harmful to pipelines, but also the landslide and debris flow caused by landslide and debris flow threaten the safe operation of pipelines. Therefore, long-distance pipelines need to adopt hydraulic protection measures. Through the survey, we can see that at the time of the construction of long-distance pipeline projects, the mountainous areas and river courses along the pipeline will cause more serious disturbance to some extent. The concrete manifestation is that the functions of original soil and water conservation will be reduced and the rate of water and soil loss aggravated , This will inevitably cause a great deal of the area around the pipeline
