| Summary: | The authors consider varied engineering actions aimed at the protection of pipelines from developing erosion processes with a focus on the conditions of northern regions. Engineering solutions, considered in the article, include prevention of erosion processes along pipelines, protection from suffusion, protection of extended areas having the limit value of the slope angle, and actions aimed at the drainage of areas along pipelines. Prevention of erosion processes along pipelines consists in the restoration of the fertile layer using biological methods, as well as the volumetric soil reinforcement using geological grids. Prevention of suffusion processes consists in the employment of various types of suffusion shields accompanied by the application of geotextile. Berms are constructed as suffusion prevention actions in extended areas having a limit value of the slope angle. This action is used to reduce the water flow energy of drainage ditches and trays along the pipeline. The authors believe that a complete geotechnical monitoring network must be designed and developed to monitor the condition of pipelines and foundation soils. Рассмотрены различные варианты мероприятий инженерной защиты трубопроводов от активизирующихся и развивающихся эрозионных процессов преимущественно в условиях северных регионов. Рассмотрены технические решения на участках вдольтрассовой эрозии, участках развития суффозионных процессов, технические решения на протяженных участках с предельной величиной угла наклона естественной поверхности, а также мероприятия инженерной защиты по осуществлению вдольтрассового водоотвода. |
