Abstract
In greater Tokyo, there are plans to construct new belt highway and ring road toreduce terrible traffic congestion in the urban area But it is difficult to constructhem because there is so much infrastructure which was constructed over pastyears above ground and shallow underground. It is necessary of using the deep underground, and we must construct connecting sections of tunnel without cut and cover method. The highway needs long changing lanes, so new a construction methodthat stabilizes tunnel structure of connecting section without obstructive pillars is required. The objective of this research is to propose this new method, reinforcing shield tunnel with transverse arched structures and ground anchors without pillars in the connecting section, and analyze dynamics behavior of this compound structure.
