抄録
A new method called the Stress Compensation-Displacement Discontinuity Method (SC-DDM) is proposed for the Homogenization Analysis of 2-dimensional Multi Joint Set Problem.<BR>Mechanical behavior of the rock mass which contains many joint sets within is dependent upon the joint set geometry and condition, such as the number of joint sets, the joint length, the joint interval, the aperture of joint and so on, and concerns with the loading condition including the orientation of loading. In order to analyze the mechanical characteristics of such a rock mass, the homogenization is successfully applied in the present paper, together with a stress compensation scheme. An infinite structure of rock mass is homogenized using a unit cell which is a representative structure of microscopic, and the macroscopic behavior is defined and analyzed basing on the fundamental response of the unit cell analyzed numerically by the Displacement Discontinuity Method.<BR>In the present paper, the theory and practice for the analysis of the stress intensity factor around the tip of joint are mainly presented and discussed, along with the the stress compensation scheme of indispensable for the analysis of the infinite structure. The case studies of a single open joint set problem are performed using a latticed model and an alternative model, and the usefulness of the SC-DDM is made clear.
