    Deformability analysis of infinite jointed rock mass by the RCOD

    By K. Sugawara, Y. Hirakawa, A. Sato

    The rock mass properties such as deformability and permeability are highly dependent on the existence of cracks. The Ratio of Crack Opening Dependency (RCOD) was proposed as a new index to evaluate th

    A quantitative evaluation of the load bearing capacity of ground and characteristic curves of tunneling

    By T. Nishimura, H. Kiyama, K. Wakimoto

    Discussion on the load bearing capacity of ground and the stability of tunnel is presented. We derive a simplified solution of a circular lined-tunnel in an elastic ground. The solution results in a b
