Effect that Synthetic Fiber has on Cohesion and Internal Frictional Angle of Xi-ge-da Soil

Abstract

Xi-ge-da strata is widespread in Pan-xi region, the physical-mechanical properties of which is specila compared with general soil. The study of reinforcement in Xi-ge-da strata possesses applicable value in engineering. The result and change law of c and φ of Xi-ge-da strata with Synthetic fiber has been obtained by three-axial compression test. It is founded that the result of c and φ has risen by 35.9% and 33.8% respectively compared to the one without Synthetic fiber. It provides basis data for the use of reinforcement in Xi-ge-da strata.
