摘要
在TBM地下组装洞室的实际开挖过程中,因围岩节理、裂隙、控制爆破、人为操作等的影响,个别洞室段岩台开挖未能成型。针对TBM组装洞室开挖过程中的未成型岩台,文中提出了不同程度未成型岩台的处理方法,并以HJ隧道工程TBM1-1(4#支洞组装洞室)为研究背景,对结果进行了验证,对同类工程提供了参考依据。
In the actual excavation process of the TBM underground assembled cavern, the rock benches of the individual cavern are unshaped because of the influence of the surrounding rock joints, cracks, controlled blasting,artificial manipulation, and so on. According to these unshaped rock benches in construction of the TBM assembled cavern, the paper puts forward the treatment methods for the unshaped rock benches with the different degree,takes the HJ tunnel engineering TBM1-1(4# branch tunnel assembled cavern) as the research background to verify the results, which could provide some reference basis for the similar projects.
