厦门填海土的振动台试验研究

应用振动台对厦门填海土做了一系列模型试验，试验结果表明：该填海土的动孔压有一定的滞后性，规律性较差；其残余应变受加速度和密度的影响较大；残余应变的值很小，最大只有0．15％左右，据此算出的地基震陷变形为毫米级。根据试验结果分析，建立了填海土的振陷经验公式。

TESTING STUDY OF SHAKING TABLE ON MADE-LAND SOIL IN SEABEACH OF AMOY

A series of model tests are made on the made-land soil in the seabeach of Amoy by using shaking table. The testing results show that dynamic pore pressure is of hysteresis to some extent. When the vibration stops,the dynamic pore pressure also raises for a period. The residual strain of the made-land soil is much affected by acceleration and density. As the maximum residual strain is about 0.15%,the vibration depression of foundation is of the order of millimeter. According to the test results,a residual strain formula of the made-land soil is established.
