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.
By shearing test and shearing creep test,the shearing properties and shearing creep properties of cement filled joint are researched.Firstly,the marble is used to make tensile-type joint,and the joint is then filled with cement.Secondly,the direct shearing test for the cement-filled joint is conducted;and the deformation properties and failure pattern are obtained.Thirdly,the direct shearing creep test is furtherly conducted;and the creep deformation properties and failure pattern are also obtained.Finally,the test results are analyzed.The research deepens the knowledge of deformation and failure properties,which is the foundation for the research of shearing strength and creep model for cement-filled joint.
