Outline of Research at the Start

常に浸透流にさらされている土構造物は,細粒分の流失やパイピングといった内部浸食を受けており,時間とともに劣化していく.本研究は,実験・数値解析を通じた,繰返し負荷条件下での浸食の進展過程の解明と,地震や豪雨・洪水といった偶発作用に対する耐災性に影響する浸食形態・程度の解明を目的とする.本研究により,耐災性低下が懸念される個所やその健康寿命の推定が可能となれば,社会資本の全体最適化に向けた社会資本ストックのマネジメント高度化の一助となることが期待される.

Outline of Final Research Achievements

Earthen structures subjected to repeated seepage flow, such as levees or dams, are often deteriorated by internal erosion. In this study, by focusing on suffusion, i.e., one of the modes of internal erosion, the process of deterioration of soils due to the migration of fine particles is identified and the vulnerability of the erosion-deteriorated earthen structures against earthquakes/floods is demonstrated through physical model tests and numerical simulations.

Academic Significance and Societal Importance of the Research Achievements

常に水の浸透流に曝されている土構造物は内部浸食により劣化していると考えられる.本研究の成果は,そのような土構造物の内,地震や豪雨・洪水に対する耐災性低下が懸念されるものの洗い出しや,土構造物の健康寿命の推定に資するものであることから,社会資本の全体最適化に向けた社会資本ストックのマネジメント高度化の一助となることが期待される.
