Problems solved by technology

figure 1 The advantages and characteristics of the unit division are for the purpose of convenient calculation. The stratum is inclined, but it is still divided according to the horizontal or vertical, or directly divided according to the delaunay triangle, so as to satisfy some convergence conditions in mathematics, and the expression in mathematics is simple and reasonable. However, the development law of strata and the respective characteristics of mutation and continuity are ignored.

Embodiment 1

[0043] The present invention adopts a method for constructing a two-body geological model as a technical solution, and the construction method uses a two-body form of geological structure physical property mutation surface and full space unit division to construct a geological model;

[0044] The specific steps of the construction method of the two-body geological model are:

[0045] Step 1: The pre-processing process, that is, the establishment of the geological structural plane: the geological structural plane is the sudden change of the physical properties of the geological body, and the interface is distributed in a certain range and the interface is continuous, including the interface of different strata due to different ages, and the difference in lithology interface, unconformity surface, fault plane;

[0046] Obtain geological survey data, including drilling, survey lines, geological points, topographic surveying, trenching, pit surveying, adit, rock formation measurem...

Abstract

The invention discloses a method for constructing a two-body type geologic model. According to the construction method, a two-body type construction geologic model with divided geologic structure physical mutation surface and total space unit is adopted. According to the method for constructing the two-body type geologic model disclosed by the invention, an underground geologic model can be expressed by virtue of computer software, namely the expression of the geologic structure is combined with physical continuity expression of a geologic body so as to be used for expressing a three-dimensional geologic model, so that the mutability can be considered, the continuity can also be considered, and the accuracy of expression and research of the geologic model is ensured. Moreover, the thin-layer unit is further separated to form micro units, the unique geologic body space can be expressed by each micro unit, the geologic model has high authenticity and accuracy, and scientific research and geological detection are conveniently performed.

Description

technical field [0001] The invention relates to a construction method of a geological model, in particular to a construction method of a two-body geological model. Background technique [0002] The description and expression of the physical properties of underground geological bodies is the premise of engineering geological calculation, engineering design, and construction. The method of expression determines the method, accuracy, and convenience of subsequent calculations. At present, there are two ways to express geological bodies, one is to express geological structural planes, which represent the abruptness of geological bodies, which are geological interfaces, faults, unconformity planes, etc. , and the whole space is directly divided into units, and each unit is endowed with different attributes to express the continuity of geological bodies. These two models have been retained for a long time, and have corresponding software support. The more commonly used geologica...
