Fatigue Test of Basalt Fiber and Polypropylene Fiber Soil-Cement

Cement-soil is a common method to strengthen soft soil foundation. In engineering construction, certain amount of fiber often added improve its mechanical properties. order evaluate the fatigue damage properties soil-cement materials under cyclic loading, basalt and polypropylene were into in this experiment carry out material test loading. The results show that compared with plain soil-cement, anti-fatigue ability significantly enhanced. Under condition same incorporation ratio, improved than fiber. load level, higher cement ratio is, greater strength more cycles failure are. log-linear relationship between stress level life obtained through test, which can be used calculate times different levels.
