In this paper, we examine the mechanical behavior of shaft excavated by short-step sinking method, as part of the researches to verify the applicability of engineering technologies. Concretely, the shaft behavior during excavation is analyzed with FEM to estimate the deformation and stress state of rock mass and concrete lining support. Next, we actually measure rock mass deformation around the shaft and compare them with FEM analysis results. In addition, we apply inverse analysis method to short step sinking shaft in order to understand the shaft behavior better, and finally summarize the technological points to enhance the accuracy of inverse analysis method.

In the Mizunami Underground Research Laboratory (MIU), two 1,000m-deep shafts and several research galleries are being constructed. Water inflow into the shafts during shaft sinking is disturbing the project progress. As a countermeasure for this problem, post-grouting is being considered and post-grouting test has been undertaken in one of the shafts. This report gives an outline of the work plan and results of the post-grouting test.
