Example Embodiment

[0042] The embodiments of the present invention will be further described below in conjunction with the drawings.

[0043] Such as figure 1 As shown in --7, a physical similarity simulation test device for inclined rock formations is composed of an external frame, a tiltable frame, front and rear baffles, hydraulic support devices, and suspension lifting devices; among them:

[0044] The external frame includes two vertical columns 3, a transverse base 2, an upper beam 1 and a double pulley track 5. The horizontal base 2 is fixed on the ground by bolts, and a parallel double pulley track 5 is installed on the inner lower end surface of the upper cross beam 1. The left and right vertical uprights 3 are fixed together with the base 2 and the upper cross beam 1 by bolts.

[0045] The outer frame has a length of 5m, a height of 3.8m, and a width of 0.4m. Among them, the left and right columns are four-sided steel plates with length × width × height of 0.2m×0.3mm×3.6m respectively; the ...

Abstract

The invention discloses a physical similar simulation test device and a physical similar simulation test method for tilted stratums. 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...
