Embodiment Construction

[0035] Such as figure 1 As shown, the test platform 1 for accommodating a large-scale three-dimensional physical model usually adopts the structure of a model tank, that is, the model platform is surrounded by side walls, the upper part is open, and the side walls are often open for people to enter and exit. Working frames are often erected around the model tank , the test personnel can observe the model test process from above the side wall of the model tank.

[0036] A stakeout method for rapidly determining stakeout point positions of a large-scale three-dimensional physical model, the method comprising the following steps:

[0037] Step 1: Arranging stakeout base points 2: Arranging at least three stakeout base points 2 at the same elevation on the upper edge of the test platform 1 accommodating a large-scale three-dimensional physical model;

[0038] Step 2: Select three stakeout base points 2 for stakeout: Select three stakeout base points 2 from the stakeout base point...

Abstract

The invention relates to a setting out method for fast determining the position of a setting out point of a large three-dimensional physical model. The method includes the following steps that: step 1, setting out base points are arranged; step 2, three setting out base points are selected to carry out setting out; step 3, the three-dimensional coordinates (xb, yb, zb) of the setting out base points selected in the step 2 under a three-dimensional coordinate system are measured; step 4, the distances (D1, D2 and D3) from each setting out base point in the three setting out base points to a target setting out point Mi are calculated; and step 4, the position of the setting out point is determined, and setting out is carried out. With the setting out method for fast determining the position of the setting out point of the large three-dimensional physical model provided by the invention adopted, fast determination of the setting out point can be completed without a total station instrument required, and setting out procedures can be greatly simplified, and a point determination process is simple and fast.

Description

technical field [0001] The invention relates to the technical field of measurement and positioning applied to large-scale geotechnical (geological) three-dimensional physical model tests, in particular to a stakeout method for quickly determining the positions of stakeout points of large-scale three-dimensional physical models. Background technique [0002] The physical model test is an important technical means to study the mechanical properties and deformation characteristics of rock and soil (or geological bodies). The geometric size ratio between the physical model and the prototype object is called the geometric similarity ratio or scale of the physical model. The larger the scale, the smaller the reduction ratio of the model, and the closer the model is to the prototype, the more favorable it is to obtain test data close to the prototype. Therefore, after the prototype geotechnical body (or geological body) to be studied is determined, it is generally desired that the ...
