议注浆工艺在隧道裂隙发育地层的应用

Discussion on the application of grouting technology in tunnel cracky stratum

通过对宜万铁路赵家岭隧道溶蚀裂隙段进行现场勘查,决定采用注浆工艺对其进行处理,着重就注浆施工方案设计及施工工艺作了阐述,最后得出采用注浆技术加固裂隙发育地层是可行的。

Through field investigation on karst corrosion eracky section of Zhaojialing tunnel on Yi-Wan railway, it determines to use grouting technology for the treatment, mainly describes grouting construction scheme design and construction technology, and finally finds out that the grouting technology reinforcing cracky stratum is feasible.
