Lateral large deformation of a bolt in discontinuous rock
Abstract
Based on the new large deformation theory (i.e. Stocks-Chen Strain-Rotation Decomposition Theorem, Chen Zhida, 1979), a rational lateral large deformation model of bolt due to shear-tensile loads has been proposed in this paper. The uniform strain (& stress) theoretical formula has been derived. A new method of determining bolt deformation and internal force based on displacement measurement has also been presented. Theoretical complete curves between strength of bolted joints and bolts’ deformation have been set up. The validity of theory has been confirmed by experimental results.
