Abstract

The invention belongs to the field of rock mechanics tests, and in particular relates to a rock mechanics test device for simulating the one-side water-immersion weakening of water bank and slope rocks and a method for using the same. The technical scheme is as follows: rock mechanics test equipment for simulating the weakening of one side of water bank slope rock, including support frame, base, water tank, upper loading rod, lower loading rod, three hydraulic push rods, camera, camera and sound Launch monitoring device, the support frame is a square frame, the base is installed on the lower support surface of the support frame, the water tank is installed on the base, and the upper loading rod is installed on the support frame On the upper support surface, the lower loading rod is installed on the base, and the three hydraulic push rods are respectively arranged at the geometric centers on the left, right and back of the water tank. The push rod enters the water holding box to load the rock test piece. The invention can be used to study rock mechanical properties and slope weakening problems of water bank slopes under the condition of one-side flooding.

Description

technical field [0001] The invention belongs to the field of rock mechanics tests, and in particular relates to a rock mechanics test device for simulating the one-side water-immersion weakening of water bank and slope rocks and a method for using the same. Background technique [0002] In many engineering fields such as water conservancy and hydropower engineering, mining engineering, and road engineering, the stability of rock slopes has always been the main research direction. At present, the number of reservoirs in my country ranks first in the world, and the number of road projects and open-pit mine projects is also in the forefront of the world. Once the huge amount of engineering construction is adversely affected by complex geological conditions and water weakening, it is very easy to induce damage and instability of rock slopes. According to incomplete statistics, landslides have occurred in about 90% of open-pit mines in my country. These disasters seriously threat...
