| 摘 要： | 由于土体不同透水边界对微振液化的影响不同，选用3种隔水层与透水层的组合情况，进行现场和原位循环荷载试验和室内土样振动试验，结合试验中所观察到的现象和循环荷载作用过程中土样密度、含水率、孔隙比的变化，研究在循环荷载作用下隔水层与透水层的存在以及振动力不同的施加方向对黄河口海床土液化过程的影响。

| Abstract: | The influence on microshock liquefaction by different permeable boundaries of soil is variant. Combinations of permeable layer and confining stratum are used in the paper. Filed in situ cyclic loading test and indoor vibration testing of soil samples are made. The analysis of test phenomena and variation of density, water content and void ratio of soil sample in cyclic loading test is made to study the influence on soil liquefaction by combinations of permeable layer and confining stratum and different direction of vibration force. The soil is belonged to marine deposit of Yellow River delta. |

| Keywords: | Yellow River delta cyclic loading test permeable layer confining stratum microshock liquefaction |
