Urban shallow-buried subway construction will lead to stratum displacement and ground surface settlement.Construction process of shallow-buried subway was numerically modeled by general finite element method ABAQUS.According to calculated displacement response and stress response resulting from surrounding rock excavation

and also based on in-situ test data

influence of shallow-buried subway excavation on urban pavement structure was evaluated

and the meaning of decreasing of pavement structure additional flexural tensile stress due to presupported surrounding rock by advance long pipe roof was discussed.Analytical results show that excavation construction of shallow-buried subway with soft surrounding rock will cause remarkable stratum loss and distinct pavement surface settlement

which will lead to larger additional flexural tensile stress in asphalt concrete pavement structure

and pre-support of long pipe roof has great value to control the development of stratum loss and pavement surface settlement and decrease the additional flexural tensile stress in pavement structure due to them.
