In order to study the mechanical properties of anti-floating anchor rod in medium-strong weathered red sandstone and its application in engineering examples, this paper takes the virtual university town project of Hengyang High-tech Zone of Hunan Province as the engineering background. This paper had done destructive test of anti-floating anchor rod. The effects of different parameters on the adhesion of anti-floating anchor rod were studied by test and from three aspects: drilling depth of anti-floating anchor rod,highly and intermediary weath...
