Research of Calculation Method for Final Soft Clay Ground Settlement by Preloading Method

Abstract

Preloading method is a common way to dispose large-scale soft soil foundation, and its methods of calculating the settlement amount mainly include exponential curve method, hyperbolic method, and Asaoka method. This paper chose exponential curve method and hyperbolic method to conduct ultimate settlement calculation on some reclamation project of Yingkou Port against measured data of settlement in the project, and compared the result to that calculated by splitting summation method. The accuracy was also verified by measured data of settlement amount in later phase to reach the conclusion that hyperbolic method is more suitable for calculating the ultimate settlement amount considering the soft soil foundation of marine facies in Liaoning.
