Measured geological section method based on spatial coordinates

Abstract

The invention discloses a measured geological section method based on spatial coordinates, relates to the field of geological mapping, and solves the problems that the number of people required for field surveying in layered rock stratum regions according to an existing method is large, the drawing of an expansion graph and a projection drawing is large in calculation amount, and the process is cumbersome. The technical scheme is as follows: the measured geological section method based on the spatial coordinates comprises the following steps of drawing the expansion graph and drawing the projection drawing; the step of drawing the expansion graph comprises the steps of performing field geological mapping, determining a reference line, planning a section line, determining geological observation points and numbering, acquiring the spatial coordinates of the geological observation points, and performing geological description and measuring the occurrence; constructing a layered boundary surface, and constructing an expanded surface and the like; and drawing the expanded graph, drawing a terrain contour line and marking an azimuth angle, and finally obtaining the expanded graph of themeasured geological section. The step of drawing the projection drawing comprises the steps of performing field geological mapping, then organizing data, and finally obtaining the projection drawing of the measured geological section. The measured geological section method based on the spatial coordinates provided by the invention is applicable to the layered rock stratum regions.

Description

technical field [0001] The invention relates to the field of geological surveying and mapping, in particular to a method for actually measuring geological sections based on spatial coordinates, which is suitable for layered rock formation areas. Background technique [0002] The measured geological section generally starts from the old stratum and proceeds to the new stratum, that is, the baseline points from the old stratum to the new stratum. In the process of field survey, it is necessary to determine the baseline and plan the section line, in which the section line needs to pass through and have good visibility conditions. During the survey period, it is necessary to collect statistics on the rock combination, stratigraphic division, stratigraphic sequence, rock metamorphism degree, contact relationship and the characteristics of each geological unit in the work area, that is, to collect data. After the survey is completed, the data will be sorted into projection diagra...
