Abstract

A new kind of anchoring option is researched. The results show that the optimal scheme is feasible and effective. The main steps and programs of the static tension test are introduced. The testing and calculation methods of bond stress are introduced. Based on the actual engineering data, the research of bond stress under design tensile is proposed. A simplified model of the bond stress is established according to the experimental data. The results of checking show that bond stress distribution curve and the simplified model agree with the experiment. Maximum error is less than 7.2% and 7.0% respectively.
