Grid-based three-dimensional geological models of the update method

摘要

Launched a three-dimensional geological modeling study, based on contours, borehole data and profile data to establish a three-dimensional geological data and, based on contour features and drilling data were presented to the grid modeling method, further establishing the grid layers stitched into a grid formation of three-dimensional geological model. In the establishment of geological model, the relevant data associated with the geologic bodies and classification, making the data in a particular area changes, to quickly determine the regional impact of the change, and change the region to re-model and replaced data changes to resolve the problem of re-modeling; Finally take Xiangjiaba hydropower station for example, establish the corresponding three-dimensional geological model of the grid to verify the significance of theoretical study and the value of practical application.
