High and steep dangerous rock mass is located in the dangerous hidden area of slope,and its stability is very important for the design and construction safety of geological engineering.However,it is difficult for traditional surveyors to get close to the dangerous rock mass for detailed investigation and research,which is difficult to meet the needs of complex engineering.In recent years,intelligent equipment repre-sented by UAV photogrammetry technology has been widely used in the geological investigation industry with its advantages of high efficiency and high precision.This paper discusses the application of proximity measurement technology in the structural plane survey of high and steep dangerous rock mass in the form of practical engineering cases.The research results show that this technology can quickly and accurately es-tablish a detailed three-dimensional model of dangerous rock mass,assist the stability analysis of dangerous rock mass,and has important ref-erence value for the innovation of dangerous rock mass investigation technology.
