Centrifuge Model Test on Excavation-Induced Failure of Soil Slopes Overlying Bedrock

Zhao, Yiying / Zhang, Ga

Abstract A great proportion of slopes are located on the bedrock, and the excavation at the slope toe often induces the slope failure. In this paper, centrifuge model tests were performed to investigate the excavation-induced failure of soil slopes overlying the bedrocks. The slope failure mode could be categorized to two types: sliding along the bedrock or failing inside the soil. The slopes underwent significant progressive failure process, and the failure mechanism could be described with a significant coupling of deformation localization and failure. The bedrock shape influenced the deformation localization and induced different failure morphology.
