摘要
文章通过沉管隧道节段接头抗剪机理室内缩尺模型试验,测试了接头在不同接触应力状态及不同剪力键垫层厚度等工况下,混凝土剪力键与接触面摩擦力协同抗剪受力模式。结果表明,摩擦力对接头抗剪强度贡献显著而且可靠。
By scale model tests,it proves the mechanism mode of shear resistance borne by friction of contact area and concrete shear key in different contact stress states and cushion thicknesses of shear key.The results show that friction plays a significant role on shear resistance of element joint.
