specific Embodiment

[0054] For a water conservancy and hydropower project in Tibet, the survey results at the feasibility study stage revealed that the structural planes in the dam site area can be divided into as many as 9 groups according to the inclination and inclination angle, and the structural planes are very well developed, and these dominant joint groups are not evenly distributed in the bank slope , but presents great variability, that is, the distribution characteristics of structural planes in different parts can appear significantly different. For this reason, the research work needs to conveniently count the distribution of joints in different parts and under different conditions, so as to better serve the engineering evaluation. This requirement of real work requires that the spatial position information should be used in the statistical analysis of the geological structure plane, and the targeted statistical analysis of the structural planes of different engineering parts should be...

Abstract

The invention discloses a structural surface statistical analysis method based on a spatial position containing pole contour diagram, and the method provides a comprehensive analysis structural surface statistical analysis method based on the spatial position containing pole contour diagram. The method includes the following steps: step 1: aiming at a bore hole or an adit exploration object, original data is input into a database after preparation according to a suggested format and standard, an input condition for structural surface statistical analysis is formed; step 2: inquiry and statistics analysis of a structural surface sample are performed, namely, a statistical sample of a structural surface of a target part which is a targeted engineering part is obtained according to the disclosure depth or a pile number of the structural surface in a bore hole or an adit comprehensively; step 3: structural surface statistical analysis based on the spatial position containing pole contour diagram is performed, namely, aiming at the structural surface sample obtained through inquiry and statistics in the step 2, furthermore deepening statistics analysis such as dominance grouping, distribution constant calculating and the like is developed; step 4: traceablility analysis is performed, namely, any assigned structural surface is grouped, output and positioned into a three dimensional visualization interface, and the traceablility analysis is developed.

Description

technical field [0001] The invention relates to the technical field of geological survey and analysis, in particular to a structural surface statistical analysis method based on an isodense map containing spatial position poles. Background technique [0002] In the field of rock mass engineering, geological structural planes often play a controlling role in unloading, deformation and destruction of engineering rock masses such as slopes and underground caverns. Therefore, on-site investigation and analysis of geological structural planes are the main tasks of geological work. one of the contents. Existing survey work on geological structural planes is based on drilling, leveling and other exploration means to catalog and obtain the original information such as the outcropping position and occurrence of structural planes, and after necessary in-house sorting, the maps that meet the daily production requirements are formed. Data basis for drawing and statistical analysis of g...
