Description

technical field [0001] The invention belongs to the technical field of water-rock chemical dynamics, in particular to the simulation test technology of water-rock chemical dynamics. Background technique [0002] The chemical interaction of water and rock is a very important factor affecting the weathering process of surface rocks. Because the reaction mechanism is very complex and can significantly change the engineering properties of rock mass, it has long attracted the attention of scholars all over the world. The traditional water-rock interaction simulation mainly studies various geochemical reactions between water and minerals in various water-rock interaction systems and under different environmental conditions from the perspective of chemical thermodynamics. Under natural conditions, a large number of geological facts reflect that the chemical interaction of water and rock is often unbalanced, which is related to the kinetic reaction rate of water-rock interaction und...
