Abstract：Refer to the main erosion components of soluble salt of saline soil in Golmud area of Northwest China,sulfate and chloride single salt solutions and composite salt solutions are set up to carry out long-term immersion erosion test of fiber reinforced concrete.The effects of different erosion ions and different fibers on the deterioration process of concrete were studied.The deterio-ration model of fiber reinforced concrete is established based on Wiener process to predict the service life of concrete.The results show that 1.5%steel fiber and 0.3%basalt fiber can improve the corrosion resistance of concrete,and the steel basalt mixed fiber concrete can play a positive synergistic effect and have better corrosion resistance;Sulfate attack has great damage to the internal structure of concrete,while the erosion of concrete mass is more serious under chloride attack;The reliability model established by linear drift one-dimensional Wiener process has high fitting degree and can better predict the residual life of concrete.
