Abstract:
Based on the analysis of loading path of flat dilatometer test in Jingjiang area situ, with standard stress path triaxial system produced by GDS of UK used, laboratory simulation on stress path of flat dilatometer test (DMT) were carried out. Many geologic parameters are acquired, such as lateral pressure coefficient, horizontal coefficient of subgrade reaction and vertical drainedconfined tangent modulus, by analyzing the laboratory experiment result. The comparative analysis between DTM and laboratory experiment showed that differentiation on result, especially on lateral pressure coefficient and horizontal coefficient of subgrade reaction, but a little differentiation on vertical drainedconfined tangent modulus.
