岩石水化学损伤的机理及量化方法探讨

提出了化学损伤概念，分别运用化学成分分析理论、能量观点、考虑化学操作的破坏力学方法，分析了岩石水化学损伤机理，并探讨了其定量方法。采用水－岩反应的大模式与小模式理论，解释了自然界中岩体的剧烈变形及破坏往往发生在暴雨或人类工程活动时的原因。探讨了岩石水化学损伤定量方法的研究途径，提出并分析了岩石水化学损伤的层次分区性。重点讨论了考虑化学损伤的破坏力学方法，认为此方法可以解释并定量分析水－岩反应的力学效应。

ANALYSIS ON MECHANISM AND QUANTITATIVE METHODS OF CHEMICAL DAMAGE IN WATER-ROCK INTERACTION

The concept of chemical damage is given and expounded. The mechanical effects of chemical damage from water and rock interaction are related to many complex processes. The mechanism of the mechanical effects of water-rock interaction on rock is explored by using the theory of chemistry,rock failure mechanics with chemical damage,the modeling method and the energy point of view. Using the theory of large mode and small mode on chemical action of water-rock,the reason why the strenuous deformation and failure of rock mass frequently occurred after torrential rain or human engineering activity in natural world is expounded. The ways of quantitative methods for the chemical damage of water-rock interaction are approached. The division into districts of the chemical damage levels in rock is proposed. The rock failure mechanics with chemical damage is a new analysis method proposed by author. The method may explain and quantitatively analyze the mechanical effects of water and rock interaction.
