Outline of Research at the Start

自然斜面における流動地下水脈の動態を現地調査と室内試験により解明するとともに,斜面移動速度予測法を適用し,実測値に基づいた従前よりも高度な斜面危険度予測法を提案する。具体的には,
①:地温センサによる流動地下水脈の動態観測と孔内水位と移動量観測
②:物理探査による自然斜面構造の可視化とせん断試験による強度特性の計測
③:地下水の化学分析と年代測定による地下水の押し出し現象の解明
④:①~③を踏まえて実測値に基づいた斜面移動予測法を構築し,的確な斜面防災・災害軽減対策に資するための斜面危険度評価法の提案
である。

Outline of Final Research Achievements

We carried out monitoring of ground temperature, borehole water level, and groundwater dating to clarify the dynamics of flowing groundwater in the landslide mass. In addition, we attempted to replicate the moving velocity of landslide by the model based on the equation of motion combined with a damper (Lumped Mass Damper Model).
The results were shown that 1) the increase of groundwater (borehole water) level in the mass was not only caused by the process of ordinary rainfall seepage reaching the groundwater base level but also by pore air in the mass pushing out deep groundwater, 2) the above-mentioned model was able to replicate the moving landslide velocity in a simple manner, furthermore, was possible to determine the effect of countermeasures in a time-series basis.

Academic Significance and Societal Importance of the Research Achievements

学術的な意義は,地すべり滑動に関与する孔内水位(間隙水圧)の上昇が,従前からの降雨浸透過程の他に,詳細な地すべり土塊の地温変化の計測より,豪雨時の浸透過程で土塊内の間隙空気が深部地下水を押し出すことが判明した。ダンパーを組み合わせた運動モデルにより,地すべりの移動速度を時系列的に再現できたことである。
社会的意義は,斜面防災の観点から,前者の調査を斜面上で面的に展開することにより,効率的かつ効果的な地下水排除工の位置選定が大いに期待できること,後者の手法を対策工施工時に併用することにより,簡便かつ時々刻々と対策効果の評価が可能になることである。
