Pore Water Pressure Changes in Large Sand Specimen during Shaking Table Tests
作者 翁作新陳家漢
英文摘要
For the study of the behavior of saturated sand, especially liquefaction, under two-dimensional earthquake shaking, a physical model test using a large laminar shear box on the shaking table at the National Center for Research on Earthquake Engineering in Taiwan was developed. The sand specimen inside the shear box is prepared by the wet sedimentation method from a specially made pluviation device. The uniformity, density and saturation of the sand were checked by mini-cone penetration tests and P-wave velocity measurements. Pore pressures within the soil, displacements, accelerations, and velocities of the frames of various depths were measured during tests under both one-and two-dimensional shaking. It is found that the excess water pressures generated during a two-dimensional shaking are higher than those generated under one-dimensional shaking of the same magnitude. The sand at a shallower depth is more susceptible to liquefaction than the sand at a greater depth.
