抄録

In this paper, we evaluated the sensitivity of each support members for displacement control by using FEM analysis. Furthermore, we measured the support member stresses and examined a limit of displacement capacity. The following things arefound out as the result. 1) Shotcrete linings have effect on displacement control after complete closing of linings. 2) Rock bolts have effect on displacement control without closing of linings. 3) The reduction of support can be attempted when about displacement is permitted setting up the displacement capacity which makes 150mm a limit.
