摘要
Abstract
Water rock interactions occur constantly in nature,and the wet dry cycle under acidic conditions is one of the im-portant water rock interactions.In order to study the effect of wet dry cycles on the mechanical properties of sandstone under acidic conditions,0,5,10,and 20 wet dry cycles are conducted on white sandstone using solutions with pH values of 3 and 7.The me-chanical properties of white sandstone are studied after different cycles.The experimental results show that the strength of sandstone decreases after different cycles,and the impact of acidic environment on sandstone strength is particularly significant.With the in-crease of cycle times,the impact of wet dry cycles on sandstone strength gradually decreases.The prediction model established based on this has certain guiding significance for predicting the strength of sandstone under dry wet cycles.关键词
