LG-1: Full Scale Level Ground Large Scale Shaking Test on loose sand deposit

Test LG-1 involved a 5 m deep, loose saturated clean sand deposit constructed inside laminar box at the U. at Buffalo using a hydraulic fill technique. Box was imparted with input base motions of 0.015g, 0.02g, 0.03g and 0.1g provided as artificial sinusoidal motions using actuator assembly at University at Buffalo. Excess pore pressures and settlements in the sand deposit were recorded. The liquefaction in various areas of sand in the box was analyzed.试验LG-1的试样为一处5米深的松散饱和纯净砂层，该砂层通过水力填筑法在布法罗大学（University at Buffalo）的层流箱（laminar box）内填筑成型。随后该层流箱借助布法罗大学的作动器组件，施加了幅值分别为0.015g、0.02g、0.03g及0.1g的人工正弦基底输入运动。试验过程中记录了砂层内的超孔隙水压力与沉降变形，并对箱内砂体各区域的液化现象进行了分析。
