Application of Flexible Reinforcement on Anchored Cave Dwelling Based on Numerical Calculation with Rheology

Abstract:

Pointed to character of flexible support of cave dwelling on prestressed anchor for geotechnical engineering, rheological mechanics was used to analyze support effects,and a new viso-elasto-plastic rheological model was built with locked minimum load formula abtained.Such is the property that bonding soil,surrounding soil,bolts and arc surface were studied.And the finite difference method(FLAC^3D) with C++ and inline FISH program were applied to analyze stress, anchor,plastic state,shear strain rate and displacement distribution.Based on calculated results and investigation on spot, plenty of key parameters on whole bonged and prestressed bolt were studied. The numerical calculation is coincident with testing factors.So the theory basis is provided for effective support engineering.
