Creepage experiment system automatically controlling times of disturbance

Abstract

The invention relates to a creepage experiment system automatically controlling times of disturbance. The system comprises a rheometer bracket, wherein the middle upper part of the left end of a vertical part of the rheometer bracket is connected with fixed ends of a pressure rod and a turn-back lever; the turn-back lever is located at the lower end of the pressure rod; a disturbance loading system is arranged at the top of the pressure rod; a support point is arranged between the bottom end of the pressure rod and the turn-back lever; a triaxial pressure chamber is arranged at the bottom endof the pressure sensor and arranged at the top of a horizontal part of the rheometer bracket; and a free end of the pressure rod is connected with a scale pan through a connecting rod. According to the creepage experiment system, the disturbance time can be precisely controlled by a time relay in an experimental process; the disturbance loading system can automatically apply a disturbance load; and the experimental precision is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of creep test systems, in particular to a creep test system that automatically controls the number of disturbances. Background technique [0002] With the construction of various underground projects and the construction of deep mine chambers, the rock mass in a long-term stable creep state is vulnerable to dynamic disturbances such as blasting, which can induce damage and even instability of the rock mass, causing major disasters and even casualties. The coupling effect of disturbance rheology makes it difficult for the rock to exist in the stable creep stage for a long time, resulting in damage or even destruction of the rock. The existing disturbance creep experiment device needs artificial disturbance loading, which leads to the limitation of the disturbance size, the disturbance load acting on the sample is small, and it is difficult to analyze the creep disturbance under high stress loading conditions;...

AI Technical Summary

Problems solved by technology

The existing disturbance creep experiment device needs artificial disturbance loading, which leads to the limitation of the disturbance size, the disturbance load acting on the sample is small, and it is difficult to analyze the creep disturbance under high stress loading conditions; Secondly, the control of the disturbance loading time is not accurate enough, and it is difficult to quantitatively analyze the time factor
