抄録(和):
本研究は, フィルダムなどの斜面表層部の地震時安定性の検討, 模型実験における振動解析などを対象とした低い拘束圧下の土の動的変形定数について, その主要因子の影響の仕方や程度を調べ, さらに従来の高い拘束圧下の結果との比較を通じて外挿の可否に関し議論した.clean sand では広い範囲の拘束圧(σm=1〜500kPa)で変形定数の特性に大きな相違が認められないことなどを示している.

DYNAMIC DEFORMATION CHARACTERISTICS OF SANDY SOILS UNDER LOW CONFINING PRESSURE
|
抄録(英):
Dynamc modulus of rigidity and damping coefficient of sandy soils under low confining pressures (less than around 20 kPa) were investigated in the present study. Series of cyclic simple shear tests in which horizontal inertia force is applied on the surface by use of a shaking table apparatus were performed on Toyoura sand and a compacted sandy soil. Some features associated with deformation parameters such as their dependencies on confining pressure and shear strain amplitude were examined, and the results were compared with those of cyclic triaxial and torsional shear tests conducted under routine high confining pressures in order to discuss characteristic differences and correlation between parameters obtained in low and high stress ranges.
