摘　　要：根据试件的预制缝与宽度方向夹角大小的不同,制作了四种不同的试件,并进行了轴拉试验,模拟水力与外力联合作用下混凝土的复合型断裂破坏特点,并结合双K断裂理论,得到两种加载方式下混凝土的起裂和失稳断裂参数。According to the differences between the precast joint and intersection angle in width direction,the paper makes four kinds of trials,undertakes the axial tension test,simulates the damage features of the mixed-mode fracture of concrete under the hydropower and external force,and concludes the concrete cracks and unstable fracture parameter of the concrete under two loading approaches by combining with the double K fracture theory.

关 键 词：混凝土 水力劈裂 复合型断裂 双K断裂参数
