无人机摄影测量技术对构造裂隙参数提取的方法研究
Research on the method of acquiring structural fracture parameters using unmanned aerial vehicle photogrammetry technology
摘要
Abstract
In high-level radioactive waste geological disposal projects,the surrounding rock serves as a natural barrier within the multiple barrier system.The structural fractures developed within the rock can affect the stability and hydraulic conductivity of the site's surrounding rock,and potentially become pathways for the migration of radioactive nuclides into the biosphere.To ensure the safety over 10 000 years,the characteristics and spatial distribution patterns of structural fractures are of great significance for the site selection and site characterization of high-level radioactive waste geological disposal repositories.Therefore,research on the identification of structural fractures and the acquisition of their characteristic parameters is particularly important.Based on the Beishan Exploration Tunnel project,which was completed in the Shiyuejing section of the Jiujing sector in the Beishan pre-selected area for high-level radioactive waste geological disposal in Gansu Province,unmanned aerial vehicle imagery was captured from the outcrops of granite bedrock on the surface of the Beishan Exploration Tunnel.A three-dimensional real-scene model of the under-captured area was constructed using software to identify structural fractures and acquire relevant parameters.The results,verified with manual measured data,showed that the parameters of structural fractures acquired through unmanned aerial vehicle photogrammetry technology are highly accurate.This technology can provide a new reference for measuring methods of surface structural fractures in typical granite bedrock exposed areas.关键词
