Abstract Research purposes: Large unstable soil slope has the characteristics of long deformation duration, high concealment of deep displacement and great damage of instability. According to the results of displacement monitoring and the engineering geological environment conditions of slope, the deformation characteristics of slope are studied, the displacement change mechanism is analyzed, and the deformation trend and stability of slope are comprehensively evaluated.
Research conclusions:(1) According to the analysis of surface displacement monitoring data, the horizontal displacement of slope at different positions has obvious difference, the leading edge is the largest, and the trailing edge is the smallest. (2) According to the analysis of deep displacement monitoring data, the slope is in creep deformation stage. There are two potential sliding surfaces, shallow layer and bottom layer. The shallow sliding surface buried depth of 3~10 m is about 6 m on average, the deep sliding surface is located at the soil-rock interface, buried depth of 25~51 m, and the shallow layer displacement is greater than the deep layer. (3) Comprehensive analysis of surface displacement and deep displacement monitoring data shows that slope deformation has seasonal and multi-layer characteristics, and creep deformation is in a continuous development state and an aggravating trend. (4) The research results can provide reference for the stability evaluation of large-scale soil slopes.
