| 英文摘要 | Landslides in different areas of Japan are strongly affected by various roles of weathering under different climatic contexts. In this study, different granitic and granodioritic landslide-prone regions in central to southwest Japan's bedrock and soil samples are described in terms of their physical characteristics. This aims to evaluate the different levels of weathering and their impact on landslides under variable environmental conditions. In this study, bulk density decreases and porosity increases gradually from fresh bedrock to weathered upper surface soils. As a result, pore spaces are increased due to interlocking of grains and the parent minerals change to form secondary minerals, increasing the amount of clay in the mixture. Furthermore, it is confirmed by the grain size analysis. An empirical model was developed by analyzing average yearly temperature and precipitation data (during a 30-year span from 1981 to 2010) with bulk density, porosity, and permeability coefficient to look into the effects of climate on different weathering levels. Climatic data indicated that with increasing temperature bulk density increased and porosity and permeability coefficient decreased while precipitation did not follow the same trend. It also turned out that temperature variation led to an increase in the percentages of clay size particles. In addition, it was also found that weathering is more prominent in granodioritic areas that granitic areas. Therefore, it is evident that as weathering advanced and rocks broke down into smaller pieces due to an increase in temperature, losing a significant amount of their strength which ultimately led to the substantial landslide failure. |
