浅谈铁路客运专线隧道衬砌质量缺陷处理施工技术

Treatment Construction Technology on Tunnel Lining Quality Defects of Passenger Dedicated Railway

以郑西铁路客运专线阌乡隧道二次衬砌背后空洞、厚度不足等质量缺陷处理为例,根据隧道缺陷探测实际情况确定了整治原则,并对不同整治方案从施工的可操作性、安全性以及对后期客运专线运营影响等方面的对比,介绍了衬砌质量缺陷整治关键技术、既有线施工安全保障措施和整治后效果,可为客运专线类似隧道衬砌质量缺陷的整治提供参考。

Based on the treatment of quality defects of secondary lining cavity and insufficient thickness, remedy plans were determined according to the actual situation of tunnel defect and comparison was made among different treatment plans from their feasibility, safety and impact on the future operation. The paper also introduced the key technology of treatment to the defect of lining, security measures for the safety of existing railway and effect of treatment which can provide references for similar projects.
