Abstract

Abstract

To explore the inhibition effect of polypropylene fiber on shrinkage cracks of expansive soil, the development, evolution and characteristics of surface cracks of expansive soil samples with and without fibers were qualitatively described and quantitatively analyzed at the same evaporation temperature. The results show that the polypropylene fiber has a significant inhibition effect on the cracks of expansive soil during the process of water evaporation, and the ratio γ of the number of cracks to the joint of cracks can reflect the penetration degree of cracks. The smaller the value, the stronger the penetration degree of cracks. This physical improvement method can make the polypropylene fiber connect with expansive soil as a whole, and then spread the dry shrinkage stress into expansive soil, effectively slowing down the speed of crack development, so the results can be generalized and applied in the treatment of roadbed in the area of dry shrinkage crack expansive soil.
