Analysis of Mechanical Characteristic of Systematic Bolt in Loess Tunnel under the Drawing Load

Abstract:

Based on the displacement solution of Mindlin problem, the elastic solution to the distribution of shear stress & axial force is deduced under the drawing load for mortar anchor in loess tunnel. The ultimate drawing load of systematic anchor in the sidewall is measured by means of field test based on a certain loess tunnel in Kelan-Linxian Expressway, and the forcing characteristic of the anchor is analyzed. The distribution forms of the shear stress & axial force are also discussed in different soil characteristics. The obtained results will offer the theoretical basis for the design &optimum of systematic bolt in loess tunnel, which has the guiding significance in the design and construction.
