| 摘 要： | 基于结构-荷载法隧道计算理论,分别建立了隧道衬砌结构厚度不足、材料劣化及背后空洞3种病害结构计算模型,并进行了工程实例分析,阐述了病害隧道结构安全性评价的具体方法.研究结果表明:隧道结构病害的存在,改变了其整体刚度和受力状态,降低了整体承载能力.所建立的病害结构安全性评价模型能够综合考虑隧道常见病害对结构的影响,弥补了...

| Abstract: | Based on structure-load calculation theory,the thickness deficiency model,material degradation model and cavity behind lining model of tunnel lining structure were established,also an engineering case was studied and analyzed,and the concrete method of safety calculation of tunnel structure was described.The results show that,the tunnel diseases changes its whole stiffness and force state,and decreased its bearing capacity;the safety evaluation model which estabilshed in the paper considers the impact of tu... |
