Research Of Stability Informatization Of Perious Rock Based On3D Laser Scanning Technology

Southwest strong tectonic activities, development of natural geologicalprocesses,most high slope environment is relatively poor, the complex rockmass ofhigh slope stability have become the focus in the current geologicalworkers.traditional approach of investigating high slope perilous rock is very difficultand perilous.3D laser scanning technology with high efficiency, high accuracy andremote non-contact measurement makes up the defiencies of traditional geologicalinvestigation methods,by3D laser scanning. in this paper, through gathering multipleHigh slope perilous rock mass3D date on-site, sums up a new method of perilousrock identification through3D and2D technology;and analysis of the influencefactors of rock stability, classified the acquisition difficulty factors, mainly includingboundary conditions of perilous rock, geometry size and the strength parameters ofsurface of the control structure, etc. Based on3D laser scanning technology obtain theperilous rock quantitative parameters，such as boundary conditions and geometry size,etc. The results show that the technology has the advantages such as efficient,accurate, safety and economy;study surface of perilous rock strength parameterscombined with3D printing technology, put forward structural plane shear strengthcorrection formula through indoor physical model experiment date. DevelopedPerilous rock stability information management system by quadratic programming ofPolyworks, elaborated the development process from the design to the databasedesign in detail，and introduces the software module function. The system was appliedto engineering practice, compares with the numerical simulation and qualitativeevaluation results concluded that the new system has good applicability under thecondition of engineering geology conditions. In the study basically achieved thefollowing results: (1) Through gathering multiple high slope perilous rock mass3D date on-site,summarized in the route of inspection of perilous rock by3D laser scanningtechnology. Put forward a new method of perilous rock identification through3D and2D technology.(2) Through a lot of perilous rock field investigation experience and literaturereview,analysis of the influence factors of rock stability, classified the acquisitiondifficulty factors, mainly including boundary conditions of perilous rock, geometrysize and the strength parameters of surface of the control structure, etc.(3) Based on3D laser scanning technology obtain the perilous rock quantitativeparameters，such as boundary conditions and geometry size, etc. The results show thatthe technology has the advantages such as efficient, accurate, safety and economy.(4) Based on3D printing technology and3D laser scanning technology to studythe strength parameters of structural planes, JRC3D-JCS3Dempirical formula ispresented. In combination with perilous rock structural surface3D data can be getstructural plane shear strength parameters.(5) Developed Perilous rock stability information management system byquadratic programming of Polyworks, this paper introduces the design idea andprogramming code of the software, and the functions of the system are described indetail. The system has a simple, convenient and fast advantages.(6) The application of the perilous rockmass stability information system in ahydropower station in Southwest China typical perilous rock analysis, compares withthe numerical simulation and qualitative evaluation results concluded that the newsystem has good applicability under the condition of engineering geology conditions.
