中文摘要	自密实堆石混凝土由于块石粒径较大,而无法预留试块来测定其抗压强度。回弹法作为测试混凝土抗压强度的无损检验方法,既方便又可靠。用回弹法对两个自密实堆石混凝土试件进行了抗压强度测试,试验结果表明,①自密实混凝土在1.5 m范围内的堆石体中流动可形成匀质性较好的自密实堆石混凝土体。②用回弹法检测自密实堆石混凝土的抗压强度,其结果准确性高、安全可靠。③自密实堆石混凝土28 d(天)的抗压强度可用预留自密实混凝土立方体试块的方法来控制。; The self-compacting rock-fill concrete(RFC) compressive strength can't be tested by the preformed test cubes because the size of the block stone is relatively large.The rebound method is a nondestructive testing method which can test the concrete compressive strength,and it is very convenient and dependable.The rebound method is used to test the compressive strength of two RFC specimens.Experimental results show that,① the homogeneous RFC can be formed by the self-compacting concrete flowing in the prepacked rock about 1.5m distance.② the RFC compressive strength measured by the rebound method is accurate and reliable.③ the cubic compressive strength of the self-compacting concrete can evaluate the 28 days compressive strength of RFC.
