Applied Research On Deformation Monitoring Of Masonry Structure Under Earthquake Motion Using The Technology Of Digital Close-Range Photogrammetry

With the fact that computer art and the image handle development of technology, the tradition measurement method quilt exceeds, real time film measurement becomes one kind of trend. In the measurement technology building body structure construction and the stage producing turn over, making use of a figure to take photographs, that.go along is semi-automatic or entire automatic real time monitors is an important means that structure safety monitors.We can pass one now or the digital camera continues taking photographs to asking the target monitoring to be in progress, the real time field transfers a portrait to computer middle, the automation carries out a data handling from the computer, see and then the required ultimate data on computer display screen, carry out construction site real time supervisory control and according to these data. Especially development produces in building body structure when moving round, (Rangefinder and theodolite or total station over the target point can not be simultaneously observed), solves coming being able to use figure up shot to measure now. The diversity certainly producing the field, different construction site and productive establishment since different demands, what be chosen photogram metric method and data handling method also are able to different to some extent.The structure making use of figure up shot measurement technology to shake the step body under the effect face to face carries out a multiple spot, that development, real time deformation observe all-weatherly, is very necessary, realizing and then the deformable step body structure analysis under field oscillation effect, to know deformable condition shocking every moment structure in process in field sufficiently, reach the aseismatic design perfecting step body structure further thereby, reinforce it's anti-knock function purpose. Architectural deformation monitors the main body of a book by building the body to the simplicity, the rift emphasizing the structure studying and building under having analyzed a field shocking an effect the body develops a pattern and destroys state, provide a basis to look forward to being to perfect the aseismatic design theory building body structure.This paper is divided into eight chapters:The first chapter introduces a number of papers related to the basic concepts, basic principles, which is the contents of this paper.The second chapter is the implementation part of the experiment, including preparation of experimental design and experimental basic flow. The third chapter is the use of three-dimensional time baseline parallax distortion correction of digital camera analysis. Chapter IV is the'experimental process for the development of cracks in masonry damage situation and the situation analysis of the results. Fifth chapters make use'of finite element methods to have been completed building the body structure simulation analysis under field oscillation effect and pursue the comparison having been in progress with deformation. Measurement technology does the up shot making use of a figure during that period when sixth chapters have listed graduate student study about architectural deformation of type monitors application other. The at last submits the summary and suggestion.
