摘要
该文通过室内试验揭示了饱和细砂在动荷载作用下的液化—析水—再固结动力反应过程 ,试验测得的超静孔隙水压力—时间关系曲线定量地反映了超静孔隙水压力的产生、发展和消散规律。试验结果和理论分析表明 ,动荷载作用下饱和细砂中存在着三种弹性体波———第一压缩波 (P1 波 )、第二压缩波 (P2 波 )和剪切波 (S波 )。
In the paper, the process of the dynamic response of saturated fine sand under dynamic load being liquefied, water separated and reconsolidated is described based on experiment. And the tested relational curve of excess pore-water pressure with time reflects the regularity of the production, development and dissipation of the excess pore-water pressure. The experimental result and theoretical analysis show that there are three elastic body waves in saturated fine sand under dynamic load,i.e. the first compression wave( P 1 wave),second compression wave( P 2 wave) and shear wave( S wave).
