Abstract
During the construction of the No.1 tunnel in the lower dam field of Huangjiawan Hub,the slope at the inlet collapsed multiple times.To identify the cause of the slope collapse and formulate a reasonable treatment plan,through on-site investigation,borehole sampling and other methods,the geological conditions and rock and soil physical characteristics of the engineering area were clarified.The deformation characteristics and failure mechanism of the collapsed body were analyzed and determined.According to the engineering requirements,the excavation support and phased treatment plan were proposed.The stability calculation,analysis and comparison results of the collapsed body before and after the treatment show that the treatment plan is reasonable.This research can provide technical references for the treatment of collapsed bodies in similar engineering projects.关键词
