- 出版タイプ: NA本研究では、深度300m研究アクセス坑道掘削前の先行ボーリング時に1,000L/min以上の湧水が発生した2008年10月の自然電位測定結果について、ノイズ除去に有効なデータ処理方法の検討及び、処理後の自然電位測定結果から水理地質構造の推定を行った。次に、立坑排水の一時的な停止による立坑内水位上昇後の、立坑内の地下水排水作業期間である2006年3月から4月に実施した既存の自然電位測定結果について、今回検討したデータ処理を適用し、水理地質構造の推定を行った。これらを総合して、自然電位測定の地下水流動を規制する断層や割れ目帯の分布の推定への適用性について評価を行った。その結果、ノイズ除去に有効なデータ処理方法を示すとともに、このデータ処理によって研究坑道の掘削に伴う地下水流動に起因する自然電位変化を抽出し、地下水流動を規制する断層や割れ目帯の分布を推定することができた。During drilling the pilot boring in October 2008 before construction of -300 m Access/Research Gallery, groundwater inflow more than 1,000 L/min is induced, and original signals of SP monitoring are observed. First of all in this study, we thus assess the method of data processing to extract the applicable signal from SP monitoring, and the hydrogeological structure is estimated using the treated data. Secondly, the signals of SP monitoring observed between March and April in 2006 when pumping of groundwater from the shafts are applied to the same method of data processing mentioned above. In addition, the treated data is used to estimate the hydrogeological structures more in detail. Considering all results together, the applicability of SP monitoring for estimating the distributions of major water-conducting features and faults with low permeability is discussed. As the result of this study, we conclude that it is likely that the hydrogeological structures would be estimated using the SP monitoring.
