摘　　要：本文结合广西右江百色水利枢纽工程 ,采用辉绿岩骨料 ,对准三级配碾压混凝土力学性能、抗剪 (断 )特性、变形性能、热学性能等进行试验研究 ,并对辉绿岩骨料准三级配碾压混凝土的抗裂性进行评价。The studies was associated with Guangxi Baise WRPP's design demands, utilized the diabasic aggregate that come from site locations, aimed at roller compacted concrete with quasi\|tri\|graded aggregate's mechanic property, shear(break)resistant property, deformation property, thermal property, durability etc. and assessment the break resistance property of roller compacted concrete. The results of studies would provide important informations for selection diabase as Baise WRPP's construction material, in addition, it benefit to use the technique of placing roller compacted concrete.
