Embodiment

[0023] Take a rock mass with structural plane occurrence of 270°∠45° as an example. Now according to the aforementioned method, A, B, and d are the three outcropping points on the rock mass, and their occurrences are calculated using the coordinates of A, B, and d to verify the correctness of the method.

[0024] (1) The coordinates of the three points are A(1,1,0), B(2,1,0), and d(1,2,1).

[0025] (2) Obtain the normal direction of the plane formed by three points.

[0026] Try to vector P(a, b, c), simultaneous equations:

[0027] ( 2 - 1 ) a + ( 1 - 1 ) b + ( 0 - ...

Abstract

The invention provides a method for determining the attitude of a rock mass structural plane based on measurement coordinates, which belongs to the technical field of design and construction of the constructional engineering infrastructures and aims at solving the frequent problems that tools such as a geological compass are incapable of directly measuring the attitude of the geological structural planes on site in engineering application. The method for determining the attitude of the rock mass structural plane based on measurement coordinates comprises the following steps: a. selecting a plurality of exposed points on the rock mass structural plane, and measuring the three-dimensional coordinate values of the exposed points, wherein at least three exposed points which are non-collinear are selected; b. orderly performing three-point combination on the measured exposed points according to a space order to form a plurality of planes; c. calculating the normal, the tendency and the dip angles of all the three-point planes; d. determining the attitude of the rock mass structural plane by use of the normal, the tendency and the dip angles of all the three-point planes. The method for determining the attitude of the rock mass structural plane based on the measurement coordinates is applicable to the measurement of the attitudes of the structural planes.

Description

technical field [0001] The invention belongs to the technical field of construction engineering infrastructure design and construction, and relates to the qualitative determination of structural plane occurrences, in particular to a method for determining the occurrence of rock mass structural planes based on coordinate measurement. Background technique [0002] The occurrence of structural planes is one of the basic contents of geology. Generally, geological compass and other tools are used for on-the-spot measurement. The outcrops on the surface are sporadic, and it is difficult to accurately measure the occurrence of outcrops, such as wide fault zones, etc., or the structural surface is exposed on high and steep bank slopes and other inaccessible parts, so it is impossible to measure the occurrence on the spot. In view of the above situation, in the actual investigation, it is often only possible to rely on the experience of geologists to make a rough estimate, so the sub...
