| 摘 要： | 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.

| Abstract: | 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,... |
