摘　　要：通过室内大型直剪试验,对建筑垃圾废混凝土与废砖的再生粗粒料及级配碎石的抗剪强度特性进行研究,分别选用摩尔-库仑强度理论与幂函数强度理论进行对比分析。结果表明:幂函数强度理论能较好地反映建筑垃圾再生粗粒料强度包线的非线性特性。Herein with indoor large-scale direct shear test,the shear strength characteristics of the coarse-grained material recycled from construction waste concrete and waste brick,and the graded broken stone were studied by tests,and the comparison and analysis were carried out by use of More-Coulomb strength theory and power function strength theory respectively.The results show that the power function strength theory may well reflect the nonlinearity of the strength envelope of coarse-grained material recycled from construction waste.
