(1Shanghai Xian Dai Architectural Design( Group) Co. , Ltd, Shanghai 200041, China; 2 Tongji University, Shanghai 200092, China)Abstract: As a preparation for the revising of Shanghai Foundation Design Code, a series of loading test of natural foundation was camed out on the clay or silt, which included 38 plate tests in 11 fields. The test results showed the ultimate bearing capacity of natural foundation in Shanghai is stable. Based on these testing data, it was considered better to use Hansen formula for calculating the ultimate bearing capacity in Shanghai area compared with Skempton formula. But modification must be taken into consideration in the calculation with Hansen formula.
Keywords: clay; silt, ultimate bearing capacity; plate load test
