岩石结构体风化前锋扩展机理分析初探

对岩石结构体风化过程作了较为详细的分析和总结,发现岩石的风化作用进程主要受控于风化前锋面的扩展,岩石在温度变化时产生的应力使岩石结构体向小颗粒转变;在非饱和带潮湿环境中,水分以汽态方式侵入岩石内部并开始化学风化,随着时间的增长,风化前锋逐渐扩展,岩石结构体最终转化为腐岩结构体。

Analysis on Expanding Mechanism of Rock Structure Weathering Front

This paper gives detailed analysis and summary to the weathering process of rock structure.It is discovered that the course of rock weathering mostly is dominated by the expansion of rock structure weathering front,the stress caused by the change of temperature turn the larger particles of rock structure into smaller ones;in damp unsaturated zone environment,moisture intrudes rock in the form of vapour and begins chemical weathering.After that,the weathering front spreads gradually and the rock structure is turned into a saprolite structure.
