Study on the Dynamic-Static Mechanical Parameters of Fly Ash Soil Improved by Polypropylene Fiber

Abstract:

According to polypropylene fiber improving fly ash soil and based on a lot of dynamic-static tri-axial tests, the comparative analysis is made with dynamic-static strength parameters. Using the method of regressive analysis studied on the function relationship of the parameters. The influence law of the dynamic-static strength parameters after freeze-thaw cycles is analyzed. The influence of the dynamic-static tri-axial tests c after freeze-thaw cycles had great similarity. When the C and tended to be stable, the value decreased by 8%. The last three freeze-thaw cycles had great influence to and. When the and tended to be stable, the value decreased by 11%.
