| 摘 要： | 用GDS应力路径三轴试验、振动三轴试验和振动台模型试验研究了厦门2种残积土的静动力学特性与震陷特性.发现花岗岩残积土具有剪缩特性,回弹体积模量随偏应力增大而显著提高;确定了花岗岩残积土的变形强度参数,并首次得到该土的液化曲线;建立了火成岩残积土的振动残余变形与模拟地震加速度及荷载之间的关系,并用其预估厦门填海地基的震陷量.

| Abstract: | The characteristics of statics and dynamics as well as seismic depression of two kinds of residual soils in Amoy were studied with GDS apparatus and dynamic triaxial as well as shaking table equipment.The research results reveal that the residual soil of granite presents contraction under shear and its bulk modulus of resilience increases significantly with deviator stress rising.The parameters of deformation and strength and liquefaction curve were established.The relationship among residual strain of the residual soil of magmatic rock and seismic acceleration as well as surcharge was obtained,and the seismic settlement of fill soil site in Amoy was evaluated. |

| Keywords: | residual soils contraction under shear liquefaction curve shaking table test seismic settlement |
