Rock mass dry-wet cycle damage monitoring system and method in chemical corrosion environment

Abstract

The invention relates to a rock mass dry-wet cycle damage monitoring system and method in a chemical corrosion environment. The system comprises a dry-wet cycle test box which is placed on a weighing platform; the system further comprises a chemical solution preparation container and a drying heat source supply box; the system further comprises an upper computer configured with a damage degree calculation program, and the damage degree calculation program is used for calculating the porosity according to the dry weight and the wet weight of the rock sample and then calculating the damage degree according to the porosity; the dry weight refers to the weight of the rock sample during drying, the wet weight refers to the weight of the rock sample after soaking, and the dry weight and the wet weight of the rock sample are both calculated according to the reading of the weighing table. The technical problem of how to monitor the damage of the rock mass in the dry-wet cycle process is solved, the monitoring efficiency is improved, and the accuracy of the monitoring result is also improved.

Description

Technical field [0001] The present invention relates to the field of rock mass damage monitoring. Background technique [0002] In the slope of the reservoir area, the slope rock is often in a wet or dry and humidity environment, and as the water quality changes, it is often repeatedly corroded by aqueous solution of different pH. These corrosion and cyclic effects will result in different degrees of damage and deterioration from the mechanical properties of rocks. This will develop into the landslide collapse, softening, water storage leakage, etc. Creating favorable conditions, bringing many safety hazards to the reservoir area engineering and reservoir operations. [0003] Therefore, it is imminent to conduct a chemical corrosion environment, in order to achieve this goal, in order to achieve this goal, the indoor dry and wet circulation test is performed: first carry out the sample in a water environment simulation test device, then take the test and remove the test and Place...

AI Technical Summary

Problems solved by technology

[0004] The main problems in the prior art are: 1) The drying process needs to take out the sample, multiple times of drying need to take out multiple times, the operation is cumbersome, the efficiency is low, and the sample after repeated dissolution is easy to be damaged during the taking out process, affecting The monitoring accuracy of the follow-up rock mechanics test; 2) It is difficult to integrate the rock mechanics test device with the dry-wet cycle test device, and the integrated monitoring of rock mass damage cannot be realized
