摘　　要：堆石混凝土在水利工程建设中具有十分广阔的应用前景。针对堆石混凝土冻融研究较少的现状,通过室内试验的方法,展开堆石混凝土冻融损伤性能研究,获得抗压强度和动弹模量的变化规律,结果显示堆石混凝土与自密实混凝土相比抗冻性能更优。Rockfill concrete has a very broad application prospect in water conservancy project construction.In view of the current situation of less research on freeze-thaw of rockfill concrete,the freeze-thaw damage performance of rockfill concrete is studied by indoor test method,and the change rules of compressive strength and dynamic elastic modulus are obtained.The results show that the frost resistance of rockfill concrete is better than that of self compacting concrete.

关 键 词：堆石混凝土 抗压强度 动弹模量
