Analysis of displacement evolution characteristics of reverse-dip layered rock slope based on geological geometric partition

To investigate the toppling displacement evolution characteristics of anti-dip rock slopes, Xiaodongcao-Zhengjiadagou bank slope is taken as an engineering case, and firstly, geological geometric distribution are obtained by superimposing lithology, slope, elevation raster layers through ArcGIS, partition with largest area Lower Triassic Daye Formation, bottom elevation, medium slope; based on actual surface monitoring data, spatio-temporal nephogram every half year interpolated Inverse Distance Weight method, then last assigned to thousandth superimposed obtain superposition characteristics. The results show that: obvious zone horizontal deformation mainly occurs in front middle shear deformation, vertical primarily back edge total more similar displacement; value larger than value, controls overall analysis strong located at boundary between Jialingjiang Formation (T1j) (T1d).
