Abstract
Recently, mountain tunneling method has been adopted in tunneling under worse geological conditions. In order to stabilize the face and control the ground surface settlement, a variety of supplementary construction methods have been presented, while their design criteria not steadily developed. In this paper, first of all, theory of cylindrical shell was proposed as the rational design method. Furethermore, its rationality was verified and its applicability to actual design was investigated by centrifuge model tests, cylindrical loading tests and measurement data in actual tunneling construction.
