| 摘 要： | 在进行土-结相互作用振动台试验中，最常用的盛土容器为叠层剪切箱。但目前已研制出的剪切箱还只能进行一个水平方向的剪切运动，不能满足我们对三维土-结相互作用研究的要求。本文在总结国内外研制叠层剪切箱经验的基础上，研制出了刚度可调的三维叠层剪切箱。通过三层三跨地下结构砂土夹层试验，证明了本剪切箱不但能够进行三维土-结相互作用振动台试验，而且能够很好的解决模型箱的边界效应问题。同时，针对不同试验中所选择的模型土种类的不同，可以调整剪切箱的刚度，以满足试验对降低模型箱边界效应的要求。

| Abstract: | Laminar shear container is the most common soil container in shaking table test on dynamic soil-structure interaction. A three-dimensional laminar shear container was firstly designed for shaking table test. And a shaking table test on soil-underground structure dynamic interaction was conducted. The results of the test show that the soil container eliminated the boundary effect quite well in two mutually perpendicular horizontal directions. Meanwhile, the stiffness of the soil container could be changed according to the change of the model soil, which is applicable to decrease the boundary effect |
