The physical similar simulation test device comprises an external framework, a tiltable rack, a front baffle, a rear baffle, a hydraulic supporting device and a hanging hoisting device, a similar simulation test is performed on stratums with different tilt angles by adopting the device and the method, physical mechanical performances of stress distribution, displacement change and the like inside the stratums under the action of external disturbance, ground stress, external force application and the like can be measured to obtain related technical indexes and parameters so as to research the rule of the true stratums in the process, and the effective struts can be facilitated during the construction of the stratums, thus providing a guarantee for the safety construction of the stratums.

Description

technical field [0001] The invention relates to a rock formation physical similarity simulation test device and method, in particular to an inclined rock formation physical similarity simulation test device and method. Background technique [0002] Under the action of external disturbance, in-situ stress or external force, the research on the cracking and movement of rock formations, the stress distribution and displacement changes of surrounding rocks and other physical and mechanical characteristics is an important topic in the field of geological formation research, especially in geological formations. An important guarantee for rock formation safety construction. However, due to the particularity and complexity of the geological and rock formation environment, as well as the long on-site measurement period and high cost, it is difficult to carry out systematic research and analysis on rock formation pressure and movement laws and in-situ monitoring of rock formation inte...

AI Technical Summary

Problems solved by technology

The few similar simulation test devices that can simulate inclined rock formations, because the upper part of the frame shakes and is not controlled, make the center of gravity unstable, poor stability, and hidden dangers, which often cause the collapse and slippage of the filled model; and in the model machine During the overall rotation of the frame, the simulated tilt angle is limited and difficult to control

The above-mentioned similar material simulation test device has a single function, and the rock formation conditions that can be simulated are limited, and it is impossible to realize a safe and effective similar simulation test of the rock formation dip angle.

Therefore, the existing similar simulation test devices are largely difficult to meet the needs of complex geological conditions simulation at the present stage.
