Summary
The dependence of physico-mechanical characteristics of lithified rocks upon the kind and degree of mineralogical transformations caused by invasion of hypogene liquids has been considered. The revealed dependences do not hold true under an excess of corrosive agents in the liquids whose high hydraulic pressure results in forming cavernous rocks, breccias by hydro-fracture, mineral veins, plastic deformations, faults and open jointing. Thus, the process results in specific engineering-geological properties and conditions of the rocks in the masses of the natural geological amelioration connected with hypogene origin of lithification.
Résumé
L’auteur a étudié les relations des propriétés physico-mécaniques des roches quaternaires lithifiées avec le type et l’intensité des transformations minéralogiques provoquées par l’injection des liquides hypogènes. Les résultats obtenus mettent en relief l’influence de la concentration des substances corrosives dans les liquides, et de la pression hydraulique de ceux-ci, conditions qui permettent la formation de roches caverneuses, de brèches de dissolution, de filons de minerais, de déformations plastiques, de failles et de fissures ouvertes. Ces processus ont donc pour effet de créer des propriétés géotechniques particulières et permettent une amélioration géologique naturelle des roches par la lithification hypogène.
