中文摘要	以内蒙古库布齐沙漠的风积沙为填充料,高强合成纤维土工格栅为加筋材料,在不同围压(100,200,300 kPa)下,对风积沙和不同加筋层(1、2、3)的加筋风积沙进行循环荷载作用的动三轴试验。在试验基础上,分析加筋风积沙的动应力-应变关系,探讨动荷载作用下加筋风积沙动模量和阻尼比的变化特征,计算得到不同加筋层数风积沙的最大动弹性模量和阻尼比;进一步分析得到加筋风积沙动弹性模量和阻尼比的拟合模型,并确定出其中的模型参数。
英文摘要	Using the aeolian sand in the Kubuqi Desert of Inner Mongolia as the filling material,and the highstrength synthetic fiber geogrid as the reinforced material,under different confining pressures,the cyclic loading dynamic triaxial test was carried out on aeolian sand and reinforced aeolian sand with different layers (1,2 and3 layers)(100,200 and300 kPa,individually). On the basis of the test results,the relationship between dynamic stress and dynamic strain of reinforced aeolian sand was analyzed,the variation characteristics of dynamic elastic modulus and damping ratio of reinforced aeolian sand under cyclic loading were discussed,and the maximum dynamic elastic modulus and maximum damping ratio of aeolian sand with different reinforced layers were calculated. Furthermore,the fitting model of dynamic elastic modulus and damping ratio of reinforced aeolian sand was obtained,and the model parameters were determined.
