ABSTRACT: In 1980, the Matsumoto tunnel construction at the north of Matsumoto city started at the foot of the Matsumoto plateau isolated by surrounding mountains. Tunnel seepage water was thought to originate from precipitation on the plateau. Since 1980, groundwater levels and flow rates of tunnel seepage have been measured. The amount of total seepage volume from 1980 reached about 11 million m3 while the groundwater level 2km around the tunnel decreased for the first two years but has kept uniform till now. For 25 years, tunnel seepage, river and spring waters around the tunnel have been sampled many times and water chemistry and isotopes values have been measured. Tunnel seepage for the first years during tunnel construction varied from 1 to 8 m3 per minute and in the years 1993 to 1995 it decreased from 1 to 0.6 m3 per minute. At present it is steady at 0.6 m3 per minute. 3H concentration, an indicator of groundwater age during tunnel construction, was less than 0.3 T.U. It increased and remained less than 1.0 T.U. from 2003. In contrast, 3H concentrations of river and well water on the plateau were 4 T.U. Oxygen stable isotope values and HCO3- concentration of the tunnel seepage water were uniform for 25 years. Porosity was about 10 % as calculated by tracer test and measured by sampled rocks. 46 million m3 of water was in storage in rocks above the tunnel in the plateau. Therefore, 24 % of the total pore water in rocks was drained by tunnel construction for 25 years and tunnel seepage water was estimated, from low 3H concentrations, to be the original pore water before construction.

2. ROCK SLOPE INSTABILITY MECHANISM IDENTIFICATION USING NEW STEREOGRAPHIC METHODS by John V. Smith, Associate Professor, School of Engineering, RMIT University, (GPO 2476 Melbourne, Victoria, Australia)
ABSTRACT: There are numerous mechanisms of rock slope instability. The feasible mechanisms can be identified manually by using stereographic projection. The most complex mechanisms involve interactions of multiple planes of weakness within the rock mass. The conventional approach to multiple planes of weakness is to identify the orientation of their lines of intersection relative to known envelopes defined on a stereograph. In the new approach described here, the poles to planes of weakness are joined by great circles on the stereograph. The relationship between the great circles and the daylight envelope of a slope is shown to provide a rapid and accurate assessment of the potential for the wedge sliding instability mechanism. The method is described as the circle method to distinguish it from the conventional ‘intersection’ method. The circle method also allows the critical slope angle to be identified for each feasible tetrahedral rock wedge. Multi-plane toppling mechanisms are also shown to be readily assessed by use of the circle method. The new methods of stereographic analysis improve the identification and stability analysis of multi-plane weaknesses in rock slopes. The improved assessment technique is beneficial in ensuring that correct methods of stability analysis are applied to each potentially unstable slope.
Keywords: rock slopes, slope stability, stereography, failure mechanisms
