摘要
为保障淤泥与粉质粘土段隧道进洞施工安全,解决仰拱底承载力不足、洞口沉降过大等问题,以广州某隧道施工为例,介绍钢管桩加固拱底的方法。该成功经验为今后类似地质地层段隧道进洞提供一些借签。
In order to guarantee the safety of construction for entering a tunnel at the section of sludge and silty clay and solve problems like lacking of carrying capacity for inverted arch bottom,oversize settlement of entrance and so on,the method of strengthening the arch bottom of steel pipe pile is introduced by taking the construction of a tunnel in Guangzhou as a living example. Therefore,the successful experience provides some reference for entering of tunnel at similar geological formation segment in the future.
