摘　　要：通过现场试验,比较了普通硅酸盐水泥和高贝利特水泥混凝土与基岩的抗剪(断)性能。结果表明:高贝利特水泥混凝土的抗剪断和抗剪性能优于普通硅酸盐水泥。通过线性回归得出高贝利特水泥混凝土与基岩的抗剪断应力方程为τ=1.204δ+0.278(其中,δ为剪切面上的正应力),抗剪应力方程为τ′=1.119δ+0.150。普通硅酸盐水泥混凝土与基岩的抗剪断应力方程则为τ=0.790δ+0.257,抗剪应力方程为τ′=0.683δ+0.061。对高贝利特水泥改善混凝土–基岩的抗剪和抗剪断机理进行了探讨。In-situ anti-shear（cut） performance of bedrock-ordinary Portland cement concrete was compared with that of bedrock-high Belite cement concrete on the spot.The results show that the anti-shear（cut） performance of bedrock-high Belite cement concrete was better than that of bedrock-ordinary Portland cement concrete.A linear regression formula for the anti-cut performance of bedrock-high Belite cement concrete is τ = 1.204 δ＋0.278（δ is normal stress on shear plane） and the formula for the anti-shear performance is τ′ = 1.119 δ＋0.150;The empirical formula for the anti-cut performance of bedrock-ordinary Portland cement concrete is τ = 0.790 δ＋0.257 and the formula for the anti-shear performance is τ′ = 0.683 δ ＋ 0.061.The mechanism of the anti-shear（cut） performance of bedrock-high Belite cement concrete is also discussed.
