摘要
对蒙华铁路阳城隧道洞口仰坡溜塌情况进行了介绍,针对溜塌情况采取了临时及永久处理方案,并通过加强超前支护、预注浆、加强支护参数等措施做到顺利进洞,施工过程中严格执行"快封闭、管超前、短进尺、强支护、勤量测"的方针,控制了洞口溜塌体的影响,为以后类似隧道洞口段施工提供了参考。
This paper elaborated the heading slope collapse situation of tunnel hole in Yangcheng of Menghua railway,according to the collapse situation adopted the temporary and permanent treatment schemes,and through the strengthening the advance support,pre-grouting,strengthening the support parameters and other measures to achieve smooth hole entry,strictly implemented the policy of"fast closure,leading pipe,short scale,strong support,diligent measurement"in construction course,controlled the influence of controlled collapse,provided reference for future similar tunnel hole entry section construction.
