Embodiment

[0066] The experimental data of this example comes from the DEM data of the northern mountainous area of ​​Lushan Mountain, and the grid size is 2162×2260. Based on the DEM data source, extract the ridgeline (such as figure 2 ), valley line and contour line data; then extract basin boundary surface data with inverse terrain DEM, and then automatically extract mountain boundary surface data based on ridge lines and valley lines (such as figure 2 ); Finally, combine the contour line and geological surface data to calculate the occurrence information of rock formations (such as image 3 ). The effects of the present invention will be further illustrated below by describing an example of automatically classifying layered rock slope types in conjunction with the accompanying drawings.

[0067] Such as figure 1 As shown, in this embodiment, the automatic division method of layered rock slope type includes the following steps:

[0068] Step (1), specifically includes:

[0069]...

Abstract

The invention discloses an automatic classification method for layered rock side slopes. The method comprises the following steps of (1), preprocessing a ridge line, and dividing a mountain boundary based on the ridge line for forming a side slope unit; (2), calculating side slope attitude information and bed attitude information; and (3), according to a layered rock side slope classification standard, classifying the side slopes. The automatic classification method can realize automatic classification of the layered rock side slopes and furthermore has advantages of high automation degree, high objectivity, and effective satisfaction for classifying large-range layered rock side slopes.

Description

technical field [0001] The invention belongs to the application technology of geographic information technology, and in particular relates to an automatic division method of layered rock slope types. Background technique [0002] Slope is a natural or artificial slope, which is not only one of the most basic geological environments in human engineering activities, but also the most common engineering form in engineering construction. According to different classification standards, slopes can be divided into different types: according to stratum lithology, it can be divided into soil slope and rock slope; according to rock structure, it can be divided into integral, massive, layered, fragmented There are 5 types of cracked and bulky structures and so on. Among various types of rock slopes, layered rock slopes are considered to be the most widely distributed and the simplest type of slope, so there are many related researches on it. [0003] The slope structural parameters ...
