Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Such as figure 1 As shown, a two-dimensional model test system for studying the instability process and mechanism of block-cracked rock mass in tunnels and underground engineering mainly includes (1) model test bench: the external bench is composed of a single steel frame 1 through a high (2) Hydraulic loading system: composed of a hydraulic jack 2 and a numerical control system, the hydraulic jack 2 is installed on the inside of the external steel frame, and acts on the surface of the prefabricated rock mass through a rectangular pressure plate 4, through The computer controls the pressure of the jack 2 to meet the needs of ground stress in different environments; (3) block cracked rock mass prefabrication: the solid paraffin material is used to simulate the rock mass 6, and the liquid paraffin material is poured into the cubic mold 5. After the...

Abstract

The invention discloses a two-dimensional model testing system and method for the instability process and mechanism of block-fractured rock mass. The system comprises a test bed, a hydraulic loading system and an image acquisition module. The test bed is of a closed structure and provides counterforce support for the hydraulic loading system. The hydraulic loading system is arranged on the inner side of the test bed, applies pressure to the prefabricated rock mass, and provides ground stress in different environments. The image acquisition module is arranged at the front end of the test bed and records the instability process, caused by the fact that the hydraulic loading system applies force to the rock mass, of rock blocks. A hydraulic jack is installed in the steel bed, a sheet bar acts on the surface of the formed simulated rock mass, the applying force of the jack is adjusted through a numerical control system, the requirements of surrounding rock ground stress in different environments are simulated, and the instability process of the rock blocks can be completely recorded through a high-definition image pickup system.

Description

technical field [0001] The invention relates to a two-dimensional model test system and method for the instability process and mechanism of a block-cracked rock mass. Background technique [0002] With the rapid development of my country's economy, infrastructure construction is vigorously advancing. In the construction projects in Southwest my country, the application of tunnel engineering is becoming more and more extensive. Instability of block-cracked rock mass is a common form of disaster in underground engineering. During the construction process and operation period, the tunnel engineering is prone to block crack rock mass instability, which will cause huge losses to the safety of human life and property. Underground engineering model tests are usually based on the similarity ratio and similarity theory to reduce the actual engineering into a model according to a certain proportion, and obtain relevant data to obtain relevant conclusions by performing corresponding ...
