Recently in Japan, development and research actions of shield tunneling method are launched very vigorously in any phase. These actions consist of a new joints system development adapted for automatically segments assemble, manufacturing multi-face shield machine with none unicirculer shaped cutter-face and so on. They affect to not only rationalization of construction method but also design method. This paper describes influences of design and construction conditions to joint's spring model constants in beam-spring design model of shield segment based on loading tests of segments.
