| 中文摘要: |
| 将粗骨料表面进行强化处理来放大界面效应,从材料角度研究混凝土在小变形情况下粗骨料界面与混凝土阻尼之间的关系.研究时,为了消除粗骨料表面积大小对混凝土阻尼的影响,制备了总表面积为一定值的粗骨料,配制了长方体阻尼试件,采用悬挂自由振动法来测定粗骨料表面经强化处理前后的混凝土阻尼比变化. |
| 英文摘要: |
| The concrete interface effect is largered by strengthening the coarse aggregate surface,the relationship between coarse aggregate interface and the concrete damping are studied from the material point of view.In order to remove the impact damping from coarse aggregate surface area of concrete,authors use the coarse aggregate that its total surface area are certain,and prepared some rectangular damping specimens,used hanging cuboid specimen and free vibration method to measure the concrete damping ratio changes after coarse aggregate surfaces are enhanced treatment. |
