摘要 针对十堰至天水高速公路(十天公路)某隧道运营过程中出现的路面开裂、隆起、底鼓等病害,综合考虑隧道地质、水文、衬砌结构、病害情况、施工条件、处置工期、工程造价等因素,提出一种利用桩板组合结构等代隧道仰拱的加固措施。运用有限元数值模拟计算,通过现场检测数据对比分析,结果表明该等代仰拱加固方案能够较好地控制隧道沉降变形,减少路面沉降病害,确保隧道运营安全,为类似运营隧道病害处治提供参考。

Abstract: In view of the road diseases that occurred during the operation of the Shiyan to Tianshui Expressway, such as road cracks, bulges, kick drums, etc, the reinforcement measure using pile-plate composite structure replacing of invert was proposed, comprehensively considering of many factors such as tunnel geology, hydrology, lining structure, disease situation, construction conditions, disposal period, project cost, etc. Using finite element numerical simulation calculation, and getting through the comparison and analysis of on-site test data, the results showed that the reinforcement schemes based on pile-plate composite structure replacing invert could better control tunnel settlement and deformation, reduce road settlement diseases, ensure tunnel operation safety, and provide reference for the treatment of similar operating tunnel diseases.
Key words:  cracked pavement    pile-plate combination structure    replacing invert    numerical simulation    reinforcement scheme
