震度法に基づく慣用のすべり面法が想定している土質斜面の破壊パターンと機構を解明するため,2種類の砂(一方は気乾状態,他方は湿潤状態)からなる模型を傾斜により静的に破壊する実験を行ない,その破壊特性を解明した。また,模型断面をFEM分割し,全要素間にジョイント要素を配しス数学モデルに対し,低拘束圧下の材料試験から求めた強度を用いて実験の非線形数値解析を行い実験との一致を確認し,破壊機構を解明した キーワード(和): 斜面崩壊;模型試験;滑り面;砂;有限要素法;分割法;数学モデル;材料試験 掲載雑誌(英): JOURNAL OF GEOTECHNICAL ENGINEERING 著者(英): タイトル(英): STATIC FAILURE TESTS BY INCLINATION ON MODEL SLOPES OF SOILS AMD NUMERICAL SIMULATION OF THEM 抄録(英):
In the assesment of slope stability of soil structures against earthquakes, only conventional method such as so-called pseudo-static method is approved officially in aseismic design standard and seismic response analysis method is regarded as only supplemental method in Japan. In order to authorize seismic response, it is necessary for the engineers to understand clearly the reciprocal relation between both methods. But the one concerning failure patterns set up by both methods remains unknown. In this paper, in order to clarify the mechanism resulting in each failure pattern, at first characteristics of failure supposed in conventional method will be discussed on the basis of experiments in which modelslopes of sands are to be failured statically with the horizontal gravity forcegenerated by inclination of them. Above test results will be simulated by FEM analysis combined with joint element method, then the patterns of statical failures of slopes will be clarified. キーワード(英): - 記事区分 投稿論文 区分     論文集
