土工格栅层式加筋风积砂的本构模型研究

以广泛分布于内蒙古沙漠地区的风积砂为研究对象,对不加筋风积砂和不同层数的加筋风积砂做了一系列的固结排水常规三轴试验,探讨其强度变化规律和体积变化规律,并分析加筋机理,得到加筋风积砂的本构模型,并验证了本构模型的精确性。

Studies of the triaxial compression constitutive model on reinforced aeolian sand with geogrid

This text considers the aeolian sand which is extensively distributed the desert region in Inner Mongolia as research object,not reinforced aeolian sand and add different layers of reinforced aeolian sand is done serial consolidated drained normal triaxial compression test,inquiry into it's variety regulation of stress-strain relationship and physical volume change relationship,and analytical aeolian principle,then getting the constitutive model of the reinforced aeolian sand,to test and verify the accurate...
