Abstract

The stop-hole stress characteristics under out-of-plane shear (mode III) were compared with that under in-plane tension (I) and shear (II). Drilling effect of mixed mode I & III cracks were analyzed. The result shows that drilling for mode III cracks can achieve a better effect. The stop-hole life N_i is related to component failure life N_f, elastic modulus, stress intensity factor K_I and hole radius R. The ratio N_i/N_f is linear to hole edge strain and K_I/R, through which the hole life in real bridges can be evaluated. Critical and reasonable hole diameters can also be determined after measuring K_I.
