摘要
通过自制的加载装置对13组37个混凝土圆柱体试件施加四种应力水平的压应力,在经历不同冻融循环次数后,进行力学性能试验,得到各组试件应力-应变全曲线。
The durability of concrete on the action of two damage factors of freeze-thaw cycle and preloading compressive stress was investigated. 37 concrete prisms with 13 groups were applied on four different preloading compressive stress levels by specially designed equipments. The compressive ultimate strength of concrete reduced more quickly on the mutual action of two damage factors. The higher of the preloading compressive stress was, the more quickly it reduced. The tensility of the concrete and the peak strain reduced on the action of compressive stress.
