Engineering Research Equipment Grant: Soil Resonant Column Apparatus for Hybrid Strength Testing

一个岩土工程共振柱单元能够使圆柱形土试件纵向和扭转的导出。该共振柱池将与传统的三轴加载系统一起使用，以提供一种能够承受静态施加载荷（围压、轴向压缩和扭转）以及动态纵向和扭转载荷的混合测试设备。这种混合系统将允许在大范围应力幅值和应力诱导各向异性条件下研究动态土壤特性。

A geotechnnical ressonant column cell capable of subjeccting cylindrical soil specimens to longitudinal and torsional exictation is procured. The resonant eolumn cell will be uused in conjunction with a conventional triaxial loading system to provide a hybrid testing apparatus capable of static immposed loads (confining pressure, axial compression and torsion), and dynamic longitudinal and torsional loads. This hybrid system will permit studies of dynamic soil properties under a wide range of stress amplitudes and under conditions of stress induced anisotropy.
