摘要
为深入研究公路隧道穿越洞口浅埋区软弱围岩段的施工处治技术,以广东某高速公路在建隧道为工程背景,运用地表注浆及CRD开挖工法,并结合第三方监测数据,顺利地通过了不良地质段落,为以后类似工程施工提供参考。
To further study the construction treatment technology of highway tunnel through the tunnel entrance weak surrounding rock section in shallow buried area, based on a highway tunnel under construction in Guangdong Province, using the surface grouting and CRD excavation method, combined with the third party monitoring data, this paper illustrated the treatment technology of surface deformation, which successfully the unfavorable geological section and provided the reference for the similar engineering construction in the passed future.
