AB - Effects of PTFE slide rubber bearings support vulnerable to external climate impact, for the study of PTFE slide rubber bearings capacity changes after salt freezing, using standard freeze-thaw box and the mass fraction of 3.5% NaCl solution of PTFE slide rubber bearings are respectively 20, 40, 60, 80 and 100 days of salt freezing treatment, and axial compressive performance study. Through the comparative analysis of influence of salt freezing treatment on bearing capacity, ultimate strength, stiffness, elastic modulus and other properties. In the process of loading, PTFE slide rubber bearings in the side of invagination, the other side up, four corners with warping, four side has a convex, But salt freezing treatment of the specimens than standard specimens are more susceptible to brittle failure, and plate exposure, cracks and other damage phenomenon more serious. Shear strength, shear strength, horizontal stiffness, and shear modulus of elasticity with the salt freezing time decrease with the increase of PTFE slide rubber bearings support. Attenuation curve by the least square method those 50 years of compressive strength and attenuation formula, the trend is basically accord with power function law.
