Abstract

Abstract

At present, no perfect calculation method has been found for the freeway soft foundation instant settlement quality. This paper tries to establish a calculation formula of the freeway instant settlement quality in Zhujiang delta area by starting with the main factors leading to shear deformation, and considering soil structure damage and sand well restraining displacement of soft foundation. Two calculation formulas have been obtained according to the loading larger than P c and the loading smaller than P c. Also experience coefficient was attained by the analysis of the practical data. The engineering example proves that this method is credible.
- freeway,
- mar theory,
- instant settlement,
- structural soft soil
