| 英文摘要 | Using a combination of close-range photogrammetry and three-dimensional (3-D) limit equilibrium theory, a determination method for the shear strength parameters of rock-soil mixture is presented. A close-range photogrammetry method is used for measurement of the 3-D terrain of the experimental target. AutoCAD Lisp and EXCEL VBA are used to perform 3-D limit equilibrium analysis of the stability of sliding mass and perform back-analysis of shear strength parameters. The presented method was used to determine the shear strength parameters of rock-soil mixtures at the Liyuan Hydropower Station. The 3-D terrain of sliding surface could be measured notably well using of close-range photogrammetry. The computed results reveal that the cohesion and friction angle of rock-soil mixtures were 3.15 kPa and 29.88º for test A, respectively, and 4.43 kPa and 28.30º for test B, respectively, within the range of shear strength parameters, as determined by field and laboratory tests. The computation of shear strength parameters is influenced by the mesh grid number, especially the cohesion of the rock-soil mixture. The application of close-range photogrammetry can reduce the site works and improve the computational efficiency and accuracy. |
