Research and application of geotextile construction technology for saline soil roadbeds in cold and arid regions

Le résumé fourni par la source

In order to explore the stability of saline soil subgrade in cold and arid areas, the saline soil in Korla area of Xinjiang Uygur Autonomous Region was taken as the research object. Through indoor experimental research, the salt swelling deformation rate in Korla area was obtained, and the necessity of geotextile construction technology for saline soil subgrade was clarified: laying geotextile on saline soil subgrade can effectively isolate salt, prevent capillary water from rising and surface water from penetrating, thereby avoiding problems such as subgrade subsidence, secondary salinization, and salt swelling. Finally, the construction technology of saline soil subgrade geotextile was introduced, and it was concluded that the application of saline soil subgrade geotextile construction technology will improve the quality and durability of highway engineering, and contribute to the construction of safe and stable roads in saline soil areas.
