Model test monitoring point laid three-dimensional positioner and method

Abstract

The invention discloses a model test monitoring point laid three-dimensional positioner and solves the problems of low precision and time-and-labor consuming defect of laying a monitoring element in a model sample. The positioner provided by the invention has the following structure: the positioner comprises an X ruler, a Y ruler and a Z ruler, wherein two ends of the X ruler are provided with a fixing device; the X ruler is provided with a groove, the cross section of which has a convex shape; the Y ruler is connected with the X ruler through a sliding device, which fits with the convex-shaped groove; and the Z ruler is connected with the Y ruler through a connecting device. In the meanwhile, the invention also discloses a model test monitoring point laid three-dimensional positioning method, which comprises the following steps of: firstly fixing the positioner onto a model support, then sliding the Y ruler to a corresponding position according to the scale on the X ruler so as to determine the coordinate; sliding the connecting device on the Y ruler to a corresponding position so as to determine the Y coordinate; sliding the Z ruler on the connecting device so as to determine the Z coordinate, marking on a similar embedded material after the determination of the X coordinate, the Y coordinate and the Z coordinate, and determining the position of the monitored element.

Description

technical field [0001] The invention relates to a three-dimensional positioning device and method for laying out model test monitoring points, belonging to the field of test models. Background technique [0002] At present, in order to better study the stability of underground engineering and guide design and construction during underground engineering construction, the actual construction process such as excavation and support of underground engineering can be simulated by means of geomechanical model tests and numerical simulations. The geomechanical model test can restore the real physical entity, obtain the real geomechanical state under the premise of basically satisfying the similarity principle, and simulate the construction process such as excavation in this state. [0003] The geomechanical model test relies on the sensor elements arranged in the model body to record the test data. After the test is over, the data recorded by the sensor is used to analyze the test r...
