| Abstract: | The undrained shear strength is an important index to reflect the characteristics of soft soils. The process of flat dilatometer test (DMT) can simulated the undrained conditions of soft soil adequately. It is an e ffective method in situ test to obtain the undrained shear strength. Based on th e study results from the domestic and overseas a practical formula for the calcu lation of the undrained shear strength is put forward by the contrast and correc tion with the value of S\-u from the field vane test in Shanghai,and the formul a has been validated in practical engineering. |
