Gravel soil is one of the special ground in Xinjiang Gobi area. In order to give full play to its good engineering mechanics properties, dredged foundation is usually used for transmission line foundation engineering in this area. Aimed at the selection and design problems of dredged foundation for transmission tower in Xinjiang Gobi area, the foundations applicability in this area is studied through the analysis of the load test results of dredged foundation in several gravel soil sites, based on the characteristics of dredged foundation and gravel soil in Gobi area. Stability analysis methods and design conditions of dredged foundation are proposed, which have been applied in the supported project of Xinjiang area and have achieved good economic and social benefits. The design and application of dredged foundation show that the foundation is suitable for the transmission line projects at different voltage level in Xinjiang, which can play good shear behavior of gravel soil foundation, thus having a good prospect of popularization and application.
