Problems solved by technology

Due to the lack of effective working methods in the existing interpretation technology, the final result is that a large number of outcrops have not been utilized. Determining the spatial form of structural planes is still a technical difficulty in rock mass engineering geological analysis

Embodiment

[0064] A water conservancy and hydropower project in western China, the survey results in the feasibility study stage revealed that the various types of filling structural surfaces exposed by drilling and adit at different parts of the dam site area can be divided into five dominant groups according to their occurrence, as follows: Figure 5 shown. The structural surface outcrops that cannot be judged in relation to each other when cataloging boreholes and adit, shall be named using "local number" in a single hole / cave. The powerhouse area is located on the right bank of the middle dam site, and the structural planes are relatively developed, which has potential impact on the deformation and failure modes of the powerhouse rock mass. Therefore, the research work needs to obtain the structural plane geological model of the powerhouse area to provide a model basis for engineering geological analysis and design applications.

[0065] This requirement of real work requires that wh...

Abstract

The invention discloses a method for comprehensively interpreting the shape of geological structural surfaces based on multiple outcrops. The method is composed of five parts: database establishment, dominant grouping, spatial relationship comparison, geological attribute comparison, and result output; the method is based on basic engineering conditions and geological conditions, etc., query and count the structural surface outcrop samples of the target rock mass position in the original survey data, and then use the pole isodense map technology to obtain the dominant structural surface grouping according to the outcrop occurrence; within the specified dominant grouping, according to Input the occurrence deviation constraint parameters to conduct spatial correlation search on the outcrop samples of the specified structural surface, and obtain the remaining outcrop samples with location and occurrence correlation conditions; All the target samples are consistent, so as to realize the analysis and interpretation of the spatial form of a certain deterministic growth structure plane.

Description

technical field [0001] The invention relates to a method for comprehensively interpreting the shape of a geological structure surface based on multiple outcrops, and belongs to the field of engineering investigation of rock mass engineering industries such as hydropower and water conservancy, mining, and construction engineering. Based on geological indicators such as structural type, geometric characteristics (occurrence, spatial position), structural surface characteristics and other geological indicators for geological structural surface outcrops collected by geological drilling and adit catalogues, effective analysis techniques are used to interpret different outcrops. The correlation properties of structural surface outcrops in three-dimensional space provide a basis for the construction of deterministic geological structural surface network models and related geological analysis. Background technique [0002] Geological structural plane is one of the basic components o...
