Length Parameter Optimization of Systematic Bolt in Loess Tunnel Based on the Field Test

Abstract:

The theoretical solution to the distribution of axial force in Mindlin displacement problem and the plastic radius of surrounding rock in the condition of elastoplastic homogeneous soil are deduced. Based on the results of field test, the problem of length optimization of systematic bolt in loess tunnel was discussed from the two perspectives of mechanical characteristic under the drawing force and the axial force at the location of neural point. The obtained results will offer the technical support for the length optimization of systematic bolt in loess tunnel, which has the guiding significance in the design and construction.
