| Abstract: | Statistical analyses of the CPT parameters of the shallow layer soils from East China Sea continental shelf resulted in CPT statistical values of sandy soil,cohesive soil,soft soil and upon which soil class decision chart was built up for rapid soil classification in the study area.According to the CPT parameters,undrained shear strength and sensitivity of the cohesive soil were estimated with empirical formula and the selection of the empirical coefficients was studied thoroughly,which shows that in calculating the undrained shear strength and sensitivity of the cohesive soil,the results were the most identical with the experimental results when choosing 17 and 7 as Nkt and Ns.Determination of these empirical coefficients is importance for the evaluation of the engineering conditions of the cohesive soil in the studied area with CPT technology. |
