| Abstract: | In this paper, general-purpose finite element software ANSYS10.0 is utilized to set up a finite element model simulating the backfill body of high flowing fly ash mixture filled subgrade of Zunyi-Bijie Expressway, and the mechanical response of flowing fly ash backfill body is analyzed. The paper analyzes the deformation characteristics of high flowing fly ash backfill body under the action of traffic load and deadweight, estimates the settlement, analyzes and calculates the effect of flowing fly ash on structures, which has a certain guidance effect to the design and construction of high flowing fly ash backfill. |
