Experimental Study on Physical Model of Prestressed Anchorage Mechanism of Fractured Rock Slope

Abstract

In view of some problems in the application of prestressed anchoring technology in broken rock slope, this study, combined with the prestressed anchoring project of K+276 broken rock slope of Chengdu-Chongqing Expressway (CCE), based on the field geological survey and key data monitoring, adopts physical model test to study the diffusion mode of prestressed anchor cable. The concrete influence of rock mass quality, anchor cable tensioning tonnage and other factors on the stress and deformation of broken rock slope is analyzed, and the application mechanism of prestressed anchorage technology in the reinforcement of broken rock slope is discussed.
