摘要
某不良地质隧道施工初期支护出现严重的扭曲、挤压、剪断和急剧下沉等病害,并且初期支护已侵入二衬净空,针对此现象探讨如何在隧道施工中,安全、快速地解决此类问题,并对其进行了原因分析,有针对性地提出了隧道支护长距离变大形处治技术。
Aiming at the deformation phenomenon of serious twist, squeeze, shear and rapid subsidence in a tunnel primary support and intrusion phenomenon of primary support into secondary lining, this paper analyzes the countermeasures to solve these phenomenon safely and fast, and puts forward treatment technologies for the tunnel with long distance and large deformation support.
