    • Abstract
  • The deformation of geotechnical materials under the external loads generally non-uniformly varies with time and distribution. However, the search radius or search range is conventionally invariable with all the experimental images analyzed through the whole process, as well as with the measuring points in one picture. The relevant search of the image pixels in such a case is conventionally conducted based on DSCM during the basic mechanical experiment and the model experiment research of the geotechnical materials, which is too straightforward to be efficient. In order to solve this problem, a new method named PDSS which can adjust the search range is proposed to increase the efficiency. This method starts with the measurement of grid displacement covering the whole scope of analysis. The separation distance of grids is comparatively large, and the statistics are gained through the conventional search method during this period. Then, what we acquired first will be used for the analysis of measuring points. Finally, the search range of any point will be fixed with the maximum displacement of the reference element node. Such a range can be adapted for the deformation of measuring points. Essentially, the efficiency of analysis is improved through reducing the number of pixels when the PDSS is applied. As is shown from the experimental results, the analysis speed can be increased by more than 10 times. PDSS can be used to solve the problem of fast DSCM analysis for rock and soil materials with spatial and temporal heterogeneity. The research results can further improve the application level of DSCM in experimental studies of geotechnical engineering.
