... field measurements with seismic monitoring system aim to obtain knowledge on when and where it occurs in relation to orebody extraction, fluid injection, and hydraulic fracturing (Cai et al., 2001, Urbancic and Trifu, 2000, Trifu and Urbancic, 1996). Then, the numerical simulation of induced seismicity...

... Abstract: The seismic response analysis is typically carried out to evaluate the seismic resistance of the civil engineering structure including the surrounding bedrock related to nuclear power facilities. The bedrock is conservatively assumed to be a linear material in the seismic response...

...-lmm and the peak accelerations during slipping were very large with 10 2 -10 5 m/s 2 (Ohnaka 2003). These results are quite different from case of medium/large earthquakes, slip amount of 10cm-lm, peak acceleration of 1-10 m/s 2 . relation contact surface true contact area stick-slip...

...) At the initiation of sliding, the inertia terms are zero so that the following relation is obtained: tan = tan s (5) The above relation implies that the angle of inclination (rotation) at the initiation of sliding should correspond to the static friction angle of the discontinuity. If the normal inertia term...

... the water content. Table 2 gives the physico-mechanical properties some rocks of Shimajiri formation at natural state. Figure 6 and 7 show the mechanical responses of rocks. Aydan (2013) and Aydan et al. (2014) have studied the relations between NPI and various mechanical properties of soft rocks. Fig. 8...

..., Okinawa, Japan K.Sugiura & A. Sakamoto Tobishima Corporation, Nagoya Branch, Nagoya, Japan ABSTRACT: There is now a great concern how to deal with potential damage resulting from the collapse of abandoned room and pillar mines in relation to the anticipated Nankai-Tonankai-Tokai mega earthquake...

... stress tensor. The constitutive law relating the Cauchy stress tensor to the resultant strain tensor is described as = D : , where D is the Hook s elasticity tensor and is the strain tensor defined as (u) = su . Note that s is the symmetric part of the spatial gradient operator . Using the test...

... of rock slopes during earthquakes are of great concern in rock engineering works such as highway, dam and nuclear power plant constructions. The main objectives of the study are to investigate the dynamic response of slopes and likely forms of instability of the slopes in relation to the number...
