The Application of Cellular Automata in the Dumping Site Analysis

Abstract:

Based on Cellular Automata method，The article developed the HHC-CA model which generated the granular samples of different fabric to characterize the heterogeneous and random distribution of samples group．Then by means of FLAC3D，conducting triaxial numerical simulation tests of granular samples and acquiring the average cohesion C and average internal frictional angle of different relative height．In addition，on the basis of on-site survey of granular size distribution，the slope model of current situation，had considered the features of particle size grading，was established according to Xiyuanlin 413 step dumping site．The results of slope stability analysis indicated that the upper displacement vector，whose displacement direction maintained the same direction of the current situation slope of Xiyuanlin 413 step dumping site，performanced for subsidence．The middle displacement vector showed shear and the displacement vector of bottom had slightly the trend of anti-lift．The slope failure model of current situation expressed in crack at the top platform and shearing out with a arc in the middle．This status of current situation slope was temporary steady stage．
