First, considering the volume expansion process of corroded bolt, the displacement model of mortar inner surface leaded by bolt corrosion is established after the loss of corrosion production is denoted by a filling factor. Second, based on elastic theory, the mortar cracking process is analyzed after the concept of influence coefficient of surrounding rock is introduced in the course of analyzing, and the degree of cracking course affected by surrounding rock parameter is also analyzed; the finite element method is adopted to verify the results.
