| In this study, a method for estimating the in-situ stress state of NC clays using piezocone penetration test (PCPT) results is proposed. The proposed method is based on a correlation between the PCPT results and strength increment ratio. According to proposed method, no additional testing procedure for collecting undisturbed soil sample is required, which can reduce overall testing cost. To verify this method various analytical solutions were adopted and used. Measured result and predicted result are compared with each other. The verification sites consist of a variety of soil conditions. From the comparison, it is seen that predicted value of effective strcss using the proposed method match well those from measured results. |
