| Abstract: | The theories and methods related to the application of piezocone test(CPTU) in the investigation of expressway subgrade.Based on the t est results of piezocone tests in the investigation of the experimental section of Huai-Yan Expressway,the soil stratification is made,and the coefficient of c onsolidation and the undrained shear strength of soft clay are estimated.Compari ng with the boring records and the testing data from laboratory tests and vane s hear tests,it can conclude that CPTU is suitable to estimate the parameters of s oils. |
