The Shanghai Airport Link Line is the first project to use monolithic prefabricated arc part in a large-diameter tunnel in China.At present,there was no special research on the selection and layout of arc part.To address this issue,this paper studied the arc parts calculation methods and layout forms based on standard ring + left turning ring + right turning ring,left turning ring + right turning ring and universal wedge ring.The results show that,the forms of arc parts based on standard ring + left turning ring + right turning ring and universal wedge ring can better meet the engineering needs,and it is suggested that the two forms of arc parts and layout can be considered in the future projects.
