摘要
在原位条件下,采用自行研制的大型剪切设备,分别对混凝土与砂岩体和粉砂岩体两种接触面进行剪切试验,研究接触面的剪切变形和剪切强度特征。结果揭示出剪应力变化与剪位移的关系,以及接触面破坏模式与抗剪强度的关系。
A self-developed large shearing equipment was used for shear tests on two contact interfaces in situ： concrete-sandstone and concrete-siltstone, to study the characteristics of their shear deformation and shear strength. The results reveal the relationship between stress change and displacement, as well as that between contact surface destruction modes and shear strength
