摘要
通过雷达检测对衬砌结构进行分析确定出衬砌缺陷类型及范围,运用有限元软件ANSYS就衬砌钢筋缺失对衬砌结构安全性的影响进行研究,得出钢筋缺失在衬砌不同位置的结构内力(轴力和弯矩),通过检算和对比从而确定其安全性及提出处理意见。
Through radar detection, the type and scope of lining defects are determined by analyzing lining structure. By using the finite element software ANSYS, the influence of missing lining rebar on the safety of lining structure is studied, and the structural internal forces （ axial force and bending moment） are obtained in different positions of missing rebar lining. Through calculation and comparison, the safety is determined and the treatment suggestions are put forward.
