Embodiment 1

[0046] An embodiment of the present invention provides an indoor test device for multi-field observation and prediction of fault activation, including: a plexiglass box, a solenoid valve, an air pump and an information collection device.

[0047] The plexiglass box is hollow inside and the top is open; the plexiglass box is surrounded by the bottom plate, left side plate, right side plate, front side plate and rear side plate, and the connection between adjacent plates is equipped with right-angle steel frames to play the role of fixing and supporting . A number of air bags are fixedly placed on the bottom plate, left side plate, right side plate and rear side plate of the plexiglass box; the filling and deflation port of the air bag is controlled by a solenoid valve, which is connected to the air pump; the solenoid valve and the air pump are located outside the plexiglass box.

[0048] The information acquisition device includes: a strain field change acquisition and processi...

Embodiment 2

[0064] The present invention also provides an indoor test method for multi-field observation and prediction of fault activation, referring to Figure 5 shown, including:

[0065] S11: Determine the thickness and position of strata and faults and the dip angle data of faults according to the principle of similarity ratio. Different geological structures can be simulated by using different formations, thickness ratios and positional relationships of faults, and fault dip angles. In addition, it also provides a large amount of training data for the optimal prediction model of structures.

[0066] S12: Fixedly place a number of air bags on the bottom plate, left side plate, right side plate and rear side plate of the plexiglass box according to preset rules, and arrange control valves and air pumps accordingly; the specifications and inflation states of the air bags are the same. The solenoid valve can accurately realize the change of the gas volume in the air bag, and then accur...

Abstract

The invention discloses an indoor test device and method for fault activation multi-field observation and prediction. The device comprises an organic glass box, an electromagnetic valve, an air pump and an information acquisition device; the organic glass box is defined by a bottom plate, a left side plate, a right side plate, a front side plate and a rear side plate, and right-angle steel framesare arranged at the joints of the adjacent plates. A plurality of air bags are fixedly arranged on a bottom plate, a left side plate, a right side plate and a rear side plate of the organic glass boxrespectively; an inflating and deflating port of the air bag is controlled by an electromagnetic valve which is connected with an air pump; the fault activation movement process under different geological conditions is simulated by changing the inflation and deflation states of the different airbags; the information acquisition device performs distributed sensing and dynamically captures data of athree-dimensional strain field, a displacement field, a temperature field and a geoelectric field. Through the advantage of three-dimensional visual dynamic monitoring of multiple physical fields, the change characteristics of a stress field, a displacement field, a temperature field and a geoelectric field at the fault are obtained, and then the fault activation degree is analyzed and the faultactivation trend is predicted.

Description

technical field [0001] The invention relates to the technical field of engineering monitoring model manufacturing, in particular to an indoor test device and method for multi-field observation and prediction of fault activation. Background technique [0002] In some areas with complex geological conditions, due to the influence of active faults, some geological disasters will occur, such as earthquakes, formation of ground fissures, landslides, etc., resulting in traffic jams, economic decline, and ecological environment damage in some areas. It may even endanger people's lives. Mine geological disasters such as gas outburst, roof fall, rock burst and water inrush in underground mining projects are mostly related to fault activation, which seriously affect the safe and efficient mining of coal mines. The study of fault activity has always been the focus of research in the field of geological engineering. The monitoring and evaluation of fault activity can provide important ...
