[6] conducted indoor compressive strength test and CT scan test of calcareous cemented feldspar sandstone with different pH solutions and proposed a rock chemical damage model that can be applied to acidic solutions to quantitatively describe the process of rock dissolution; [PERSON] et al. [7] conducted dissolution kinetics test and uniaxial compression test on limestone and calcite under acidic hydrochemical solution corrosion and established the dissolution kinetics equation and strength damage equation of limestone and calcite specimens; [PERSON] et al. [8] conducted indoor simulated acid rain solution marble immersion test and uniaxial compression test to study the effect of acid rain corrosion on the uniaxial compression properties of marble. As for the dynamic mechanical tests, [PERSON] et al. [9] conducted static and dynamic load coupling tests on red sandstone immersed in acidic solution for 30 days and analyzed and summarized the fractal dimension and related laws after rock fragmentation; [PERSON] et al. [10] conducted the dynamic tensile test on limestone specimens corroded by acidic mixed chemical solutions at different times with the separated Hopkins pressure bar and explored the dynamic tensile strength, dissipated energy, and transmission energy of limestone with the change of corrosion damage degree; [PERSON] et al. [11] used the Hopkins pressure bar test system to conduct a dynamic compression test on marly limestone, silt stone, and pale red limestone specimens after maintenance with different acidic and neutral chemical solutions and investigated the effects of chemical corrosion and chemical corrosion-temperature coupling, chemical corrosion-damage coupling on the dynamic properties of the rocks and their mechanisms. Many deep rock mass engineering structures both at home and abroad have been subjected to long-term hydrochemical corrosion, such as groundwater [12], which is generally alkaline in nature, and its resulting chemical corrosion, as one of the important factors affecting the long-term stability of underground engineering structures, has a non-negligible weakening effect on the strength, deformation, and damage characteristics of rock masses, which has attracted the attention of scientific researchers at present. In terms of static tests, [PERSON] et al. [13] analyzed the effect of corrosion by different chemical solutions on the strength of sandstone through the uniaxial compression test and came to the conclusion that the stronger the alkalinity of the chemical solutions, the greater the effect on the corrosion of sandstone, namely, the greater the decrease in the strength of sandstone specimens. [PERSON] et al. [14] conducted a triaxial compression test on granite after immersion in different alkaline solutions, and the results showed that the cohesion of the specimens increased with the increase in the pH value of the immersion solution, and the angle of internal friction decreased with the increase in the pH value; [PERSON] et al. [15] conducted a triaxial compression test on limestone after immersion in different pH chemical solutions and studied the characteristics of the effect of chemical corrosion on each stage of the full stress-strain curve of the specimens and found that the pH value was more sensitive to the peak strength of the specimens when it varied from neutral to weak alkali; [PERSON] [16] studied the variation law of macroscopic mechanical properties and macroscopic damage characteristics of weakly -cenented siltstone in different alkaline water environments in the seven mines of Danan Lake and found that the deterioration of various mechanical parameters had an obvious time effect through analysis; [PERSON] et al. [17] conducted different chemical solution immersion tests and triaxial compression tests on malmstone and concluded that the stronger the alkalinity and the higher the concentration of the solution, the stronger the effect on the corrosion of malmstone, and the reduction in the cohesion of the specimens was greater than their internal friction angle.
