Research on Dynamic Analysis and Design System of Geotechnical Engineering Construction Period Based on BIM Technology

Block stability is still the most common problem in the process of slope excavation and large underground excavation group of hydropower station. Because of the uncertainty of structural surface development characteristics, it is the most reliable way to evaluate the block stability and engineering influence by directly using construction geological logging data for analysis. This paper introduces the solutions and functions based on three dimensional BIM technology. It realizes geological logging, structural plane cutting, block generation and key block search, supports block stability analysis and (random) support design on the 3D model of slope and cavern excavation contour, all of these links between the implementation of the program and the system of the Internet work mode, for the construction period dynamic and design provides strong technical support.
