Embodiment Construction

[0038] 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 examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] Such as figure 1 As shown, take the survey drilling ZK157 and ZK158 in the feasibility study stage of a certain hydropower station on the Jinsha River as an example, as shown in the following table, the two drilling holes expose cracks T9 and T8 respectively, and judge whether they are the same structural plane according to the technical method of the present invention. The specific steps as follows:

[0040] (1) Obtain the structural surface properties, spatial coordinates and occurrence, see Table 1 below.

[0041] Table 1 Structural surface information table to be compared

Abstract

The invention discloses a high-definition drilling color television-based rock mass structure surface search method. The method comprises the implementation steps of extracting information such as spatial coordinates, occurrence, characters and the like of a structure surface according to geological surveying and mapping, exploratory adit geological recording and high-definition drilling color television interpretation; establishing a spatial planar geometric equation of the structure surface; comparing spatial positions and characters of two structure surfaces; and judging whether a spatial relationship between the two structure surfaces belongs to the same structure surface or not. The method is used for finding out characteristics of spatial distribution, characters and the like of thestructure surface in rock mass; structure surface information disclosed by drilling is fully utilized; the limitation of a conventional method is overcome; the search range is expanded; the search reliability is improved; and the method has the characteristics of simple operation and high reliability.

Description

technical field [0001] The invention relates to geological exploration technology, in particular to a search method for rock mass structure planes based on high-definition drilling color TV. Background technique [0002] Structural planes of various origins, scales, and properties are widely developed in the rock mass. The existence of various structural planes destroys the integrity of the rock mass and directly affects the mechanical properties and deformation failure modes of the rock mass. Therefore, an important content in engineering geological survey is to find out the development of rock mass structural planes——class I-IV structural planes and the grown-up class V structural planes, so as to evaluate their adverse effects on engineering later. [0003] To find out the development of structural planes in rock mass, the traditional method can only solve the structural planes of grades I-III with large scale and poor properties. It mainly analyzes the spatial developmen...
