Mechanical behaviour of granite in triaxial compression under chemical corrosion
摘要
Abstract
A rock triaxial testing was used to conduct triaxial compression tests on the granites samples which were soaked in three chemical solutions with different pH. The effect of chemical solutions on the mechanical properties of granites was studied. The influence of chemical solutions on strength and deformation properties of granites was investigated. The corrosion degree was evaluated by measuring the variation of pH for three solutions and the variation of mass of soaked samples. The results show that the effects of three solutions on the mechanical properties of granite are different. The triaxial strength of granite is the highest in the case of pH=10, followed by that of pH=13 and it is lowest with pH=7. The cohesion of granite increases with the increase of pH of the solution, and the friction angle decreases with the increase of pH. Furthermore, the chemical erosion mechanism on the strength of granite was analyzed. Results obtained from laboratory tests could provide experimental data for the constitutive modeling of granite with chemical corrosion.关键词
