Immersion test device and test method for simulating corrosive pressure water environment

Abstract

The invention provides an immersion test device and test method for simulating a corrosive pressure water environment. The device comprises a bracket, a pressure bearing barrel and a pressure device,a sealing cover is arranged at the top of the pressure bearing barrel through a detachable bolt, the bottom of the pressure bearing barrel is arranged on the bracket, a pressure gauge is connected toa side of the pressure bearing barrel, an upper and lower through liquid discharge hole is formed in a bottom center of the pressure bearing barrel, a liquid discharge pipe is connected to a lower port of the liquid discharge hole, a liquid discharge valve is arranged on the liquid discharge pipe, and the pressure device is connected with the side of the pressure bearing barrel. The immersion testdevice provided by the invention applies different hydrostatic pressures to acid and alkali corrosive water to perform immersion treatment on a rock sample so as to truly and effectively simulate thecorrosive pressure water environment, performs quantitative or qualitative research on the influence degrees and action mechanisms of water pressure, solution ion components, ion concentration, immersion time and the like on water-rock action according to the contrastive analysis of test results of the sample and the solution under different immersion working conditions, makes researches on basicproblems such as microscopic pores, mechanical properties and the like of rocks in the corrosive pressure water environment, and compensates the blanks and deficiencies on the researches of the water-rock action.

Description

technical field [0001] The invention belongs to the technical field of engineering geology and geotechnical engineering, and in particular relates to a immersion test device and method for simulating a corrosive pressure water environment. Background technique [0002] Groundwater is the most active factor in the geological environment. After the rock mass encounters water, the continuous physical, chemical and mechanical effects of groundwater on the rock mass, as well as the influence of water on the state of the medium, are called water-rock interactions. Water-rock interaction widely exists in the surface rock and soil and deep in the earth's crust. Under the influence of water-rock interaction, the strength and mechanical behavior of rock mass will change, which will lead to various engineering disasters. [0003] Water-rock interaction includes physical action, chemical action and mechanical action. The physical action mainly includes the processes of lubrication, so...
