Mechanism and Calculation Research on Excavation Deformation of High Layered Dip Rocky Slope

Abstract:

Based on rock Mechanical theory under unloading, according to the analysis of rock mechanics state of pre and post excavation of the layered dip rocky slope, it was found that excavation unloading cause deterioration of rock constitutive relation and structure plane’s mechanical parameters, deformation mechanism of high layered dip rocky slope was analyses when rock is at unloading condition in this study. Its deformation consists of the two parts which are rock mass unloading rock mass springback displacement and bedding-slip displacement along the rock mass discontinuity, and deduced the calculating formula of slope displacement. Research results with great guide significance and practical engineering value to similar engineering construction afterward.
