Engineering Geological Advances in Japan for the New Millennium

Abstract

New Technology and its Application: Three-dimensional miarolitic cavity distribution in the Kakkonda granite from borehole WD-1a using X-ray computerized tomography The use of X-ray CT to measure the diffusion coefficients of heavy ions in water-saturated porous media Detection of hydraulic pathways in fractured rock masses and estimation of conductivity by a newly developed TV equipped flowmeter Case studies of electrical and electromagnetic methods applied to mapping active faults beneath the thick Quaternary A new technique for rapid and non-destructive measurement of rock-surface moisture content preliminary application to weathering studies of sandstone blocks In-situ Experiments Stress estimated by using microseismic clusters and its relationship to the fracture system of Hijiori hot dry rock reservoir Strain monitoring of borehole diameter changes in heterogeneous jointed wall rock with chamber excavation, estimation of stress redistribution. Non-sorbing tracer migration experiments in fractured rock at the Kamaishi mine, Northeast Japan In-situ experiments on an excavation disturbed zone induced by mechanical excavation in Neogene sedimentary rock at Tono mine, central Japan. Site Characterization: Seismic risk assessment of an active fault system - the example of the Tsurugawan-Isewan tectonic line Geotechnical evaluation of conglomerate for compressed air energy storage - the influence of the sedimentary cycle and filling minerals in the rock matrix Time-dependent ground motion amplification characteristics at reclaimed land after the 1995 Hyogoken Nambu Earthquake Overview of the stability and barrier functions of the granitic geosphere at the Kamaishi mine - relevance to radioactive waste disposal in Japan Rates of weathering and temporal changes in strength of bedrock of marine terraces in Boso Peninsula, Japan Weathering distribution in a steep slope of soft pyroclastic rocks as an indicator of slope instability.
