Abstract

Abstract: For studying the single index criterion of lining cavities,and introducing lab large-scale model test combining the engineering example,analyzing the variety of structure bearing capacity,disease producing shapes and varying rule and so on where are different dimension cavities after lining.finding out the single health criterion of cavity: it is health where no cavities after the lining,it’s sub-health when the dimension is less than 100mm,disease when the dimension is between 100mm and 550mm,it’s sick to death if the dimension were more than 550mm．

Key words: lining, cavity, test, health, criterion

摘要： 从研究衬砌背后空洞单项指标判据出发，结合实例采用室内大比例尺模型试验，分析了衬砌背后存在不同尺寸空洞时结构的承载力大小变化、病害产生形式和变化规律等。得到了隧道衬砌背后空洞的单项指标健康判据: 隧道健康状态时背后无空洞，处于亚健康时背后空洞小于100mm，病害阶段时背后空洞介于100～550mm之间，病危阶段时背后空洞大于550mm。
