通过剪切试验和剪切蠕变试验,研究了灌注水泥浆的硬性节理面的剪切特性和剪切蠕变特性.首先,利用大理岩制作了张拉型节理面,灌注水泥浆液,形成灌浆节理面;然后,利用三轴室进行直剪破坏试验,得到了灌浆节理面的变形特性和剪切破坏特性;第三,进行了灌浆节理的剪切蠕变破坏试验,得到了灌浆节理面剪切蠕变破坏特性和蠕变变形特性;最后,对直剪试验和剪切蠕变破坏试验结果进行了分析.所得结果加深了对灌浆节理面剪切破坏及变形特性的认识,为进一步研究灌浆节理面的抗剪强度与蠕变模型,提供了前提基础.
Through the shear test and the shear creep test, the shear characteristics and the creep property of the hard jointed surface of the grouted cement slurry are studied.Firstly, the tensile joint surface is made by using marble, and the cement slurry is poured into the grout Then, using the three-axis chamber for the direct shear failure test, the deformation characteristics and shear failure characteristics of the grouted joints were obtained. Thirdly, the shear creep failure test of the grouted joints was carried out, Shear creep failure characteristics and creep deformation characteristics. Finally, the results of direct shear test and shear creep failure test were analyzed. The results obtained deepen the understanding of shear failure and deformation characteristics of grouted joints. For further study of grouting Joint surface shear strength and creep model, provided the basis for the premise.
