Abstract:

PIV，the abbreviation of Particle Image Velocimetry system，is a measuring technology system without disturbance flow field.We use this system to take high resolution images and get the velocity field by calculating the velocity vectors of every point on the image.The PIV has been installed and applied to sandbox modeling experiments in Tectonic Modeling Laboratory of China University of Geosciences(Beijing).This paper introduces the data monitoring and recording during sandbox modeling experiments，as well as data computational processes and methods of parameters，including sand grain moving velocity，shear strain rate，vorticity and so on.Quantitative simulating the deformational geometry，kinematics and dynamics using above parameters is then used with examples.The results play an important role in well understanding the deformation process and mechanism.
