摘要
为了探索岩石的吸水性与所处水环境之间的关系,选用红砂岩进行自然吸水条件与自然饱水状态下含水率测试试验,通过红砂岩含水率随时间的变化规律,表征红砂岩的吸水性与所处水环境的关系。结果表明:在自然吸水条件与自然饱水条件下,岩石的含水率随时间均呈现“快速增加—趋于平缓”的变化趋势,随着时间的增加,岩石试件的吸水速率逐渐降低,在自然饱水条件岩石的最大含水率高于自然吸水条件下岩石最大含水率,相比于自然吸水条件下,在自然饱水条件下岩石到达最大含水率的时间更长。
In order to explore the relationship between rock water absorption and water environment, red sandstone was selected to test the water content under natural water absorption condition and natural water saturation state.The relationship between water absorption and water environment of red sandstone was characterized by the variation rule of water content of red sandstone with time.The results show that under both natural water absorption and saturation conditions, the water content of rock shows a trend of rapid increase to gentle with time.With the increase of time, the water absorption rate of rock specimens decreases gradually.At the same time, the maximum water content of rock under natural saturation condition is higher than that under natural water absorption condition.
