Rock Block Slide Research Articles

福島県一ツ坪田地すべりにおける粘土鉱物および水質の特徴について

The Rock block slide occurred at Hitotsu-tsubota, Showa-mura, Fukushima Prefecture, Japan is found in an almost flat area topographically. Therefore, it seems to be the good field to investigate the geological factors led the rock to block slide except the landform factors.The present paper shows the mechanism of the rock block slide occurred in this area using geological, geomorphological and hydrogeological data obtained in this work. In this process it seems to be very important to analyses strata with interformational folding from geotechnical and mineralogical method. Especially on the characteristics of clayminerals and quality of groundwater, associated with the sliding and/or bed rocks should be studied in detail.
