KAKENHI (Grants-in-Aid for Scientific Research) 7

  1. 波浪場・地盤の連続性を考慮した連成モデルの構築と漂砂に与える有効応力の効果の解明

    地盤の波浪応答は底質の移動に影響を与える可能性があることが水理実験や数値解析により確認されている．その一方で，波浪場と地盤の圧力・流速の連続性が保障された数値計算モデルは限られており，そのために底質の移動に与える有効応力の影響を検討した研究は十分に行われているとは言い難い．本研究では，有効応力が底質の移動とそれによる地形の変化に与える影響と機構を解明することを目的として，①波浪場と地盤の相互作用が解析できる波浪場・地盤連成モデルの開発，②底質内部の有効応力の影響を考慮した漂砂モデルの提案，③有効応力の観点から見た地形変化機構の解明の3つを柱として研究を実施する．

    海岸侵食は我が国のみならず世界的に深刻な問題になっているが，その抜本的な対策工法は未だ確立されていない．その大きな原因は侵食の機構，特に沿岸漂砂の発生機構が解明されていないことが挙げられる．水理模型実験はその解明の主要な手法であるが，平面水槽は水槽側壁が波動場と沿岸漂砂に及ぼす影響が除去できず，沿岸漂砂の機構解明の大きな支障になっている．本件研究はその支障を取り除く円形水槽（円状の海浜模型のため端部がない）を用いた実験により沿岸漂砂の機構解明を行うとともに数値解析によりその発生機構を明らかにするものである．あわせてこれまで未解明のビーチカスプの生成機構の解明も行うものである．

  3. Estimation method and reduction measures of tsunami-related fire risk in ports

    This study proposed a statistical model to estimate the risk of tsunami-related fire spreading, based on data on areal conditions and damage in the Great East Japan Earthquake. The model to best explain tsunami-related fire spreading incidents in Yamada town, Otsuchi town and Kesennuma city was constructed in terms of averaged tsunami inundation depth in an evaluated grid cell (EGC), areal ratio of lost buildings in cells of the seaward side of EGC, areal ratio of lost buildings in EGC, the number of households in EGC, and existence of a dike in EGC in order of its significant impact to the estimation. Motion of an object or objects flowed on land by a tsunami was examined in a series of repeated model experiments in which an object angle to the flow direction and spatial arrangement of objects were changed as initial condition. Experimental results could affirm the debris spreading angle of ±22.5° observed in the Great East Japan Earthquake by Naito et al (2014).

  4. Study on longshore sediment transport based on circular wave basin and development of its direct simulation method

    Hydraulic model experiments have been conducted using spiral wave maker and circular wave tank to investigate generation mechanism of longshore sediment transport. In the initial stage, on-offshore sediment transport is developed to form the equilibrium beach profile. Then, the longshore sediment transport is developed by the longshore current which is caused by spacial gradient of the mean water level after wave breaking. This phenomena is confirmed by the behavior of fluoressent sand in the experiments. Flow field is investigated not only in the experiment but also the three-dimensional simulation developed by the present research. In the numerical simulation method, full nonlinear wave field in the circular wave tank and spiral wave maker is simulated.

  5. Mechanism of tsunami-induced erosion of bridge-abutment backfill and effectiveness of countermeasures

    The mechanism of tsunami-induced erosion of bridge-abutment backfill and effectiveness of countermeasures were investigated using hydraulic experiments and numerical simulations. Experimental results showed that the backfill close to the abutment was eroded and the backfill on the far side of the abutment remained relatively intact, which was a similar phenomenon to that observed after the 2011 Tohoku earthquake tsunami. From comparison with experimental data, the computational capability of the numerical model, FS3M, was demonstrated in terms of water surface fluctuation and surface profile change in the backfill. From numerical results, the process in which the backfill inside the abutment flowed out from under the landward wing was observed and the mechanism of the process was revealed in terms of bedload and suspended load transport. From numerical experiments, an increase in the soil-cover depth of the wing would be effective against the erosion of the backfill.
