Problems solved by technology

[0003] The application number is CN201010298379.0, which discloses a "three-dimensional model of rock mass slope and block slide analysis method". In this method, the area of ​​the slide block needs to be determined, and the slide block is a polygon. The results are then used for subsequent stability determination and dynamic analysis of motion forms; in this method, the common solution method using normal vectors makes the calculation steps more complicated, which is not conducive to subsequent rapid analysis

Embodiment Construction

[0012] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0013] The polygonal block on which the slope slides has n sides, and n is an integer greater than 3. The polygonal block is decomposed into n-2 triangular units; the coordinates of each vertex of the polygonal block are obtained by measuring with a laser tracker. Among them, the triangular unit The coordinates of the three vertices are: P 1 (x 1 ,y 1 ,z 1 ), P 2 (x 2 ,y 2 ,z 2 ), P 3 (x 3 ,y 3 ,z 3 ), the area of ​​the triangle unit

[0014] Among them, the values ​​of x, y, and z can be quickly calculated according to the determinant method, and the coordinates of the three verti...

Abstract

The invention provides a rock body side slope downslide block body area analysis method. A polygonal block body sliding down from a side slope has n sides, wherein n is an integer greater than 3; the polygonal block body is decomposed into n-2 triangular units; the coordinates of each apex of the polygonal block body are obtained by using a laser tracker; the area of each triangular unit is calculated rapidly by using a determinant method according to the coordinate values; the area of the polygonal block body can be obtained by summing up the area of the triangular units. When prejudgment analysis is carried out for side slope stability in the field via downslide block bodies, the analysis and calculation method provided by the invention can greatly simplify calculation steps and save calculation time during manual calculation and verification and facilitate teaching and pre-analysis in the field.

Description

technical field [0001] The invention relates to the technical field of mountain situation analysis, in particular to a method for analyzing the area of ​​a rock mass side slope sliding block. Background technique [0002] Slope stability has always been an important research content in geotechnical engineering. With the vigorous development of national economic construction, there are more and more high and steep slopes in projects such as railways, highways, water conservancy and hydropower, and mines, and the problem of collapse is more prominent. In order to prevent the occurrence of geological disasters of collapse, it is more urgent to remediate the slope in a planned and focused manner, and to analyze the stability of the slope collapse. [0003] The application number is CN201010298379.0, which discloses a "three-dimensional model of rock mass slope and block slide analysis method". In this method, the area of ​​the slide block needs to be determined, and the slide b...
