Dynamic construction method of refined three-dimensional hydrogeological model

Abstract

The invention provides a dynamic construction method of a refined three-dimensional hydrogeological model, which comprises the following steps: collecting geological data of a modeling object in a research area, analyzing structural characteristics of rock strata in the research area, and determining elevation of each rock stratum interface and dynamic characteristics of water level in a reservoir area; preprocessing and inputting the geological data; fusing the preprocessed and input geological data into a three-dimensional space through multi-source data integration to achieve integrated display, and constructing a refined three-dimensional hydrogeological model; performing dynamic exploration and model checking on the constructed refined three-dimensional hydrogeological model; and underground water level dynamic monitoring and underground water flow field drawing. According to the method, the requirement of geotechnical engineering for hydrogeological structure modeling precision can be met; the relative relation between stratums and geological structures and the intersection relation between the stratums and the geological structures and underground facilities are displayed in a targeted mode; the underground water level of a research area is dynamically monitored through the three-dimensional hydrogeological model; an underground water flow field model is generated; and formation conditions, characteristics, dynamic laws and the like of underground water are analyzed.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering modeling, in particular to a dynamic construction method of a refined three-dimensional hydrogeological model. Background technique [0002] The traditional 3D hydrogeological model construction method often adopts GIS technology, and the final 3D GIS geological model only includes stratigraphic interface information, geotechnical engineering geological information and engineering information such as faults, fractured zones, and underground facilities, which is incomplete. After sectioning, stratigraphic section information cannot be viewed, and the degree of refinement of the modeling is not high enough to fully utilize the role of the 3D hydrogeological model. Therefore, the dynamic modeling of the refined 3D hydrogeological model can accurately reflect the engineering geology and hydrogeology information of the research area in real time. [0003] Through investigation, it is ...
