滹沱河粉细砂的动力特性试验研究
Experimental Study on Dynamic Characteristics of Hutuo River Siltsand
【摘要】 通过室内动三轴试验研究了重复动荷载作用下滹沱河粉细砂的动力性质,分析了加载周期、动应力大小以及加载频率对动应变、动弹模和动强度的影响,为填砂路基的设计与施工提供了理论依据。
【Abstract】 The author studied the dynamic property of the the Hutuo River Siltsand under cyclic dynamic load by dynamic tri-axial test,analyzed the influence of load cycle,the dynamic-stress size as well as the load frequency on the strain,the elasticity mold and the dynamic strength,and provide theory basis for sand-filling embankment design and construction.
