通过循环冻融试验，探究酸侵蚀地区白砂岩冻融损伤的影响因素。研究对三组白砂岩分别作不浸泡、水浸泡、酸浸泡的处理后进行不同次数的冻融循环，再进行单轴压缩试验。并从纵波波速、峰值应力、应力-应变曲线、相对杨氏模量、损伤变量等方面分析不同处理方式的影响。研究表明：水的浸泡是白砂岩冻融损伤的主要原因，酸侵蚀能在一定程度上加快白砂岩的冻融损伤，但本实验中影响不大。研究成果对寒区及酸侵蚀区的建设及工程具有一定的参考价值。

Through circulation freezing-thawing test,the paper studied the influence factors of freezing-tha-wing damage of white sandstone in acid erosion areas.The paper firstly treated white sandstone sample with different ways such as not soaked, soaked in water and soaked in acid ,and performed freezing-thawing test at different circulation times ,then carried out uniaxial compressive strength test.It also analyzed the effect of different processing ways from longitudinal wave speed,peak stress,stress-strain curve,relatively young's modulus and damage variable.The resultsIts indicated that white sandstone of white sandstone being soaked in water is the major reason of freezing-thawing damage, and acid erosion can speed up the freezing-thawing damage to in certain extent, but the impact is not significant in this experiment.The research conclusion can provide valuable reference for the engineering construction in cold and acid erosion area.
