By analyzing the main causes of surface settlement caused by foundation pit excavation,the influencing factors of surface settlement were sorted out,and then the morphology of surface settlement under different working conditions was analyzed in depth.For the calculation method of surface settlement,the application characteristics and applicable conditions of Peck curve method,formation loss method,numerical simulation method and monitoring and measurement method are studied,and finally the surface settlement caused by foundation pit excavation is calculated and analyzed by taking a subway foundation pit project in Nanjing as an example.
