The shallow tunneling of large-section rectangular tunnels is an important project for the development of urban underground space in China.But its construction technology is complex,the surrounding environment is sensitive,therefore,effective control of ground deformation is an urgent problem that needs to be solved.Ground deformation not only has a great impact on the surrounding buildings and infrastructure,but also causes a series of social problems and economic losses.Based on this,this paper discusses the law of ground deformation and optimi-zation measures in the shallow tunneling construction of large-section rectangular tunnels.
