Abstract

The invention provides a rock and earth mass shear rheometer taking rainfall and blast vibration reciprocal actions into account. The rock and earth mass shear rheometer comprises a shear rheology unit, a dry-wet cycle unit, a blast disturbance unit and a CCD displacement automatic measurement system for detecting displacement of a lower shear box. The blast disturbance unit provides disturbance for the shear rheology unit through a rigid support and a vibration motor and simulates blast loads, and the rigid support is formed by a vertical supporting rod piece, an upper rigid rod piece and a lower rigid rod piece. The connecting positions of the vertical supporting rod piece and the upper rigid rod piece and the lower rigid rod piece are adjustable, and the disturbance transmitted to a pressurization system is adjusted to achieve disturbance loads of different strengths and quantitative simulation of blast loads in the rheological test process. According to the rock and earth mass shear rheometer taking the rainfall and blast vibration reciprocal actions into account, blast loads and rainfall reciprocal actions of different frequencies, strengths and periods can be effectively simulated in the shear rheological test process, and displacement change conditions of a sample in the test process are measured accurately to be used for quantitative research on shear rheological characteristics of rock and earth mass under the rainfall and blast vibration reciprocal actions.

Description

technical field

[0001] The invention relates to a rock-soil body shear rheometer, in particular to a rock-soil body shear rheometer considering the repeated action of rainfall and blasting vibration, and belongs to the technical field of rock-soil engineering. Background technique

[0002] The rheological properties of rock and soil refer to its deformation properties that change with time, mainly including creep, relaxation and elastic aftereffect. The rheological properties of rock and soil must be considered in major engineering design and stability analysis Key factor. As one of the most active factors in nature, water has a great influence on the deformation and strength properties of rock and soil, mainly including softening, erosion, chemical corrosion, hydrodynamic pressure, etc.; in addition, construction in water conservancy, transportation, mining and other fields Among them, blasting is a necessary procedure for slope modification, foundation treatment, ore mini...
