ResumoTo obtain basic data served to the field measurements and the design methods of sandy ground tunnels, a series of laboratory model tests and two different types of finite element analyses were performed. In the case of shallow overburden, large displacement took place even at the ground surface, while the larger displacement zone reduced its size when the overburden became deeper. The use of joint elements in the analyses was found to be more effective than of usual elasto-plastic elements to describe the discontinuous movements occured in sandy ground due to tunneling.
