摘要/Abstract

摘要： 为避免衬砌拱顶脱空危及隧道结构和行车安全,首先分类梳理拱顶脱空的成因,采用数值模拟方法分析衬砌脱空对隧道结构的力学影响;其次研发基于触压导电原理的分布式压密传感器,构建由传感器、延长线、采集终端、网关、工业电脑构成的监测系统;然后提出衬砌浇筑主动监测的工作流程、管理等级和传感器布设方案;最后结合实际工程采用地质雷达检验监测结果,验证监测方法及系统的可靠性,在多个铁路建设项目中进行示范应用。结果表明:造成衬砌脱空的原因复杂多样,拱顶脱空会显著增大衬砌应力及变形、影响衬砌安全,采用基于分布式压密传感器的衬砌浇筑主动监测方法和系统,能够实时掌握衬砌拱顶是否浇筑密实,避免拱顶脱空的形成。

Abstract: In order to avoid lining vault void endangering tunnel structure and driving safety, the causes of vault void were sorted out firstly, and the mechanical effects of lining vault void on tunnel structure were analyzed by using the method of numerical simulation. Secondly, a distributed pressure sensor based on the principle of contact pressure was developed, and a monitoring system was constructed which composed of sensors, extension lines, terminals, gateways and industrial computers. Then, the working flow, management level and sensor layout scheme of active monitoring for lining pouring were proposed. Finally, by checking the monitoring results with the ground penetrating radar in practical projects, the reliability of the monitoring system and method were verified, and the system was applied in multiple railway construction projects. The results show that the causes of lining void are complicated and varied. The vault void can significantly increase the stress and deformation of lining and affect the lining safety. The active monitoring method and system of lining pouring based on distributed compaction sensor can grasp whether the lining vault is compact in real time and avoid the formation of vault void.
