摘要:

针对公路隧道衬砌结构病害问题日益突出的现状,基于160余座公路隧道衬砌检测资料对衬砌背后空洞形态特征进行统计分析,在此基础上对衬砌结构受力性能和安全性进行了评价。结果表明:空洞主要分布在衬砌拱部位置及围岩状况较差的Ⅴ级、Ⅳ级围岩段; 空洞纵向长度主要分布在0～20 m范围,其分布曲线呈指数降低分布规律,空洞径向高度主要分布在0～25 cm范围,其分布曲线呈正态分布规律,空洞平均长度及高度按照拱顶→拱腰→边墙、V级→Ⅳ级→Ⅲ级的规律逐渐减小; 空洞高度的增大对衬砌结构力学性能影响较小,而空洞环向范围的增大显著降低了衬砌安全性,衬砌结构受力性能随空洞纵向长度增大而逐渐向着不利状态转变,但当空洞纵向长度增大到一定值后衬砌结构安全性进一步降低的幅度有限; 研究结果可为衬砌背后空洞的整治提供参考。

Abstract:

In view of the present situation of the increasingly prominent problems of the lining structure damage of highway tunnel, based on the lining inspection data of more than 160 highway tunnels, the statistical analysis of the shape characteristics of the voids behind the lining was carried out, and the mechanical performance and safety of the lining structure were evaluated on the basis. The results show that the voids are mainly distributed in grade V and IV surrounding rock sections with poor lining arch position and surrounding rock condition. The longitudinal length of the void is mainly distributed in the range of 0-20 m, and the distribution curve is exponential decreasing. The radial height of the void is mainly distributed in the range of 0-25 cm, and its distribution curve is normal. The average length and height of the void decrease gradually according to the law of vault→haunch→sidewall, V-class→Ⅳ-class→Ⅲ-class. The increase of the void height has little effect on the mechanical performance of the lining structure, while the increase of the circumferential range of the void significantly reduces the safety of the lining. With the increase of the longitudinal length of the void, the stress performance of the lining structure gradually changes to the unfavorable state, but when the longitudinal length of the void increases to a certain value, the further reduction of the safety of the lining structure is limited. The research results can provide reference for the treatment of the void behind the lining.
