Abstract
A case of using the vacuum preloading method to improve the foundation soil for a road in Tianjin, China, is presented. A vacuum load of 80 kPa was applied for 90 days to consolidate a 20 m thick soft clay layer. The ground settled for about 1·5 m. The average degree of consolidation estimated using settlement data was 90%. The undrained shear strength of the soil increased and the water content decreased after vacuum preloading. The procedures used for soil improvement, the instrumentation and the field monitoring data are described. Several issues concerning the practical aspects of the vacuum preloading method are discussed.
