INVESTIGATION OF DESIGN AND CONSTRUCTION, AND PROPOSAL ON TUNNELING METHODS FOR LARGE SECTION TUNNEL WITH SHALLOW OVERBURDEN

Abstract

Large-scale facilities such as subway station, underground car park, underground passage road were investigated on design and construction technology for constructing using tunneling methods in the comparatively shallow space for the purpose of efficient use of underground space in urban area.
In this paper, the controversial point and the problem to be solved are reported to make a correct application of tunneling methods for large section tunnel with shallow overburden.
