The Crack Limit Analysis Based on the Fracture Mechanics of the Main Arch of the Stone Arch Bridge

This paper is based on fracture mechanics to calculate the arch bridge crack spacing circle and the stress intensity factor. Then the relation between the cracks spacing limit problem is calculated. And stress intensity factor relations under the same crack length and the same pull force is discussed. Finally the analysis shows that the height of the fracture cracks into the crack width as the impact factor is feasible.
