ESTIMATION OF HORIZONTAL SUBGRADE REACTION BASED ON VIBRATION TEST USING LARGE SCALE SHEAR BOX
|

| 抄録（英）： |
Pile vibration tests using a large-scale laminar box were conducted to study the horizontal subgrade reaction (P) during soil liquefaction. The subgrade reaction depending on the relative displacement between the pile and soil (Pｄ) and depending on the relative velocity (Pv) were studied by using the Voigt model. It is shown that :1) The subgrade reaction of the non-liquefaction soil is caused mainly by the displacement. The Pd/ P is about 80%. 2) The subgrade reaction of the liquefaction soil is caused mainly by the velocity, when the amplitude of the displacement is constant. The Pd/P is about 5%. The subgrade reaction is caused by the displacement as well as the velocity, when the amplitude of the displacement increases. The Pd/P increases and becomes nearly 50%.
