A practical stability analysis method for the soft soil foundation on Pearl River Delta

Through the systematic analysis on the monitored data of the soft soil foundation of nearly 20 freeways constructed on the Pearl River Delta,a new method was developed to evaluate the stability of the soft soil foundation by the combination of the monitored data of settlement and deformation characteristics of the soft soil.The stability of the softest soil strata of the foundation could also be analyzed by the new method with the subsurface settlement.
