摘　　要：为了考虑随机地震荷载作用下饱和粉土的液化特性，研究了如何通过合理的地震响应分析确定饱和粉土层受到的随机地震荷载，进一步探讨了随机地震荷载作用下的动三轴试验技术，以及利用此种试验分析饱和粉土液化特性的方法。研究结果为形成判别饱和粉土层地震液化可能性的新方法提供了依据。In order to analyze liquefaction behavior of the saturated silt under random seismic loading, it is studied how to determine the random seismic loading acting on the saturated sill layer by means of reasonable seismic response analyses. The cyclic triaxial test technique under random seismic loads and method for analyzing liquefaction behavior of the saturated sill using the cyclic triaxial tests are further researched. Results of this paper can provide basis for developing new method to determine the liquefaction possibility of saturated slit layers during earthquakes.
