Abstract
In the analysis of the stability of rocky slopes,determining the mechanical parameters of large-scale fractured rock masses is a critical challenge that needs to be addressed.This thesis utilizes unmanned aerial vehicle(UAV)photogrammetry technology to obtain centimeter-level three-dimensional real scene models of slopes.A software called Slope RMI was developed on the VS+C#platform using the OpenGL 3D graphics engine,which identifies rock mass structural features through line and surface interactions,achieving efficient recognition and statistical analysis of structural plane characteristics based on a high-precision 3D model of the study area.Additionally,a synthetic rock mass technique with target rock quality designation as a constraint was proposed,generating a large-scale rock slope calculation model that directly integrates three elements:the mechanical properties of rock,the mechanical properties of structural planes,and the geometric morphology of structural planes.This approach circumvents the difficulties associated with obtaining mechanical parameters of large-scale rock masses and provides a reliable pathway for detailed analysis of the stability of large-scale rocky slopes.The research method has been successfully applied in slope engineering,demonstrating its significant practical value in engineering applications.关键词
