摘要在台湾国立地震工程研究中心（NCREE）的振动台上，发展了一个大型柔性层状剪切箱，用于研究饱和砂土在二维地震作用下的特性，特别是液化和土-结构相互作用。剪切盒由15层铝合金内、外框组成，试件尺寸为1880 × 1880 × 1520 mm，剪切盒内不同深度的土体可根据振动台产生的二维波浪作用而发生无扭转的运动。剪切盒内的砂样是在大型雨洪装置中采用湿沉降法制备的。安装仪器测量位移、加速度和不同位置的水压。进行了有砂试件和无砂试件的剪切箱振动台试验。试验结果表明，双轴层流箱和仪器的性能是满意的。
A large flexible laminar shear box was developed for the study of the behavior of saturated sand, especially liquefaction, and soil-structure interactions under two-dimensional earthquake shaking on a shaking table at the National Center for Research on Earthquake Engineering (NCREE) in Taiwan. The shear box is composed of 15 layers of aluminum alloy inner and outer frames with a specimen size of 1880 by 1880 by 1520 mm. The soil at various depths inside the shear box can move, without torsion, according to the two-dimensional wave action induced by the shaking table. The sand specimen inside the shear box is prepared by the wet sedimentation method from a large pluviation device. Instruments are installed to measure the displacements, accelerations, and water pressures at various locations. Shaking table tests of the laminar shear box with and without a sand specimen were conducted. The test results showed that the performance of the biaxial laminar box and the instrumentation are satisfactory.
