Abstract

The invention discloses a rock hydrologic action measurement method, which is measured by a rock hydrologic action measuring system. The rock hydrologic action measuring system comprises water contactors and water storage buckets. The water contactors are used for placing a rock sample or placing a reference mold, wherein the rock sample is a water absorbent material, the reference mold is a non-water-absorbent material, and the water storage buckets are used for injecting water into the water contactors; the rock hydrologic action measurement method comprises the following steps: step S10: placing the reference mold on the water contactor, and measuring the amount of water evaporation of the water contactor and the water storage bucket during a first predetermined time; step S20: placingthe rock sample on the water contactor and performing a water absorption test of the rock sample; step S30: obtaining the amount of water change in the water storage bucket during the first predetermined time; and step S40: calculating the amount of water absorption of the rock sample according to the first predetermined time, the amount of water evaporation, and the amount of water change. The rock hydrologic action measurement method effectively solves the problem of low test accuracy for rock adsorption in the prior art.

Description

technical field [0001] The invention relates to the technical field of engineering rock mass experiments, in particular to a method for measuring rock hydraulic action. Background technique [0002] The water environment of the rock has a great influence on the rock properties. The research on the water adsorption characteristics of the rock is currently a technical hotspot in geotechnical engineering, and it is also of great significance to the study of the permeability of the rock. [0003] In the prior art, rock hydraulic tests are usually used to study rock properties, and to study the law of water adsorption by soft rocks in deep formations under different water pressure conditions. However, when measuring the water absorption of rock samples, the amount of water evaporation is not quantitatively considered. For the impact on the water absorption of the rock sample, the evaporation of water will have a greater impact on the water absorption of the rock sample, resulting...
