超浅埋暗挖隧道初期支护结构内力监测及稳定性分析

Structural internal force monitoring and stability analysis on primary lining of bored tunnel with a shallow depth

文章以广州地铁林和村段暗挖区间工程为例,通过采用结构内力的监测手段,获得了超浅埋暗挖隧道的围岩径向压力及结构内力的分布规律,并进行了围岩压力、结构内力的稳定性分析。对类似的工程设计、施工有一定的参考价值。

Taking the construction of Linhecun section of Guangzhou metro as an example, this paper introduces the distribution law of structural internal force and radial pressure of the surrounding rock of shallow depth bored tunnel by means of monitoring. Moreover, the stability analysis in relation to surrounding rock pressure, structural internal force, construction sequence and deformation is conducted, which can be taken as a reference for similar projects in the future.
