湿度变化对岩石风化产生的影响

摘要

文章对处于不同湿度环境下的花岗岩进行了数值模拟,得到的结果将岩石的风化按照时间分为两大阶段,即风化准备阶段和风化扩展阶段.依据风化速率将风化扩展阶段分为缓慢增长阶段,低速增长阶段及高速扩展阶段.%In this paper, the granite is simulated in different humidity environment, and the results show that the rock weathering is divided into two stages according to the time: the preparation stage and the weathering stage. On the basis of the weathering rate of weathering, weathering growth stage is divided into slow growth stage, low speed growth stage and high speed expansion stage.
