The pore groundwater stores in loose sediments, which is rich in resources,excellent of water quality, and has a good development and utilization value. Long-term excessive exploitation of the pore groundwater is thrown a series of environmental and geological disasters such as land subsidence, land resource degradation, and the serious influence on the sustainable development of economy, society and environment. Pore groundwater is buried in underground. Pore groundwater with exploration, the dynamic monitoring as well as the simulation in order to understand its occurrence and migration law and resources. The groundwater flow field numerical simulation methods is to reveal the law of motion of groundwater flow and one of the main methods of evaluation resources. The rapid development of three-dimensional hydrogeology modeling technology, provides a reliable platform for the simulation of groundwater flow, it can be visually expressed pore groundwater storage and transport medium spatial structure.This paper deep research the dynamic generating technique of three-dimensional Pore groundwater flow field based on three-dimensional hydrogeological model, based primarily on a fluind-structure interaction model of pore groundwater,trying to access to relevant data about Three-dimensional geological dynamic modeling and flow visualization in order to be able to dynamic generate three-dimensional pore groundwater flow field based on three-dimensional hydrogeological model.Meanwhile,based on three-dimensional hydrogeological dynamic model and a reasonable vector field visualization,pore groundwater flow field in three-dimensional hydrogeological model achieves effective visualization and integrates dynamic simulation of pore groundwater flow field and three-dimensional hydrogeological model,thus increases the hydrogeological data of groundwater system performance, in order to further predict porosity evolution trend of groundwater systems and on the rational analysis and management of groundwater resources evaluation of science has important practical value.The investigations in this paper encircle the dynamic generating technique of three-dimensional pore groundwater flow field based on three-dimensional hydrogeological model.Main research contents:(1) The Coupling of classical soil consolidation model and equation fundaments of hydrogeology,make up the pore groundwater fluind-structure interaction mathematical model considering the3D hydrogeological structure layer deformation characteristics,to obtain the data of pore groundwater flow field and Three-dimensional geological dynamic modeling.(2) With the Collected Hydro-geological borehole data,an effective method to contrust a Three-dimensional geological model,by which the model shall be diveded into a series of small discrete three prism element space,was particularly studied.Then a dynamic data transformation algorithm was proposed to simulate the pore groundwater fluind-structure interaction mathematical model, that is,to express the Three-dimensional numerical calculation results in the three-dimensional geological mode and further more the dynamic modeling algorithm was actualize.(3) According to the groundwater flow pore formation and dynamic three-dimensional hydrogeological modeling principles and requirements, This paper investigated the generation algorithms of pore groundwater flow and integration of three-dimensional hydrogeological model.
