摘要
模拟周边缝的实际结构进行大比尺力学模型试验 ,获得了周边缝的受拉压、剪切与沉陷的变形曲线。分析周边缝三向变位特征 ,阐述了周边缝的变形机理和破坏特征 ,拟合三向受力变位关系式。
A large scale mechanics simulation test is carried out by simulating the actual structure of peripheral joint, and the consequent deformation curve of peripheral joint under the action of tension, compression, settlement and shear is acquired. The 3-D displacement feature of peripheral joint is analyzed, based on which the deformation mechanism and failure characteristics are expatiated for fitting the 3-D loading displacement relation. At last, a thin layer joint element constitutive relation model is proposed.
