ENGINEERING GEOLOGICAL PROPERTIES OF THE SATURATED CLAY FOUNDATION AT THE SOUTHERN EDGE OF MU US DESERT IN CHINA
In order to investigate the engineering geological properties of the saturated clay foundation along the Jingbian-Wangquanliang expressway, in-situ and laboratory tests had been done, including in-situ standard penetration test, cone penetration test and geotechnical tests in the laboratory. According to test results, the physical and mechanical properties of the saturated clay foundation are studied. It is found that most of the ground does not exhibit the characteristics of soft soil in the studied area, but the variation of the consolidation coefficient is relatively large, between 0.05 and 0.33 MPa-1, which may result in inhomogeneous settlement. The soft ground within the depth of 12 m shows slight salinization and serious liquefaction. Friction angle of the saturated clay is 30° and its cohesion is 10kPa. Bearing capacity of the foundation is less than 100kPa in the depth less than 3 m and less than 140 kPa within the depth less than 5 m.
