结合已有的地表注浆加固理论和施工技术,针对山底隧道弃渣堆积区选用合理的施工参数,并采用MIDAS-GTS有限元软件进行分析。注浆后,隧道的稳定性得到了很好地改善。为以后的工程设计和施工提供了借鉴。
Combined with the existing theories of surface grouting and reinforcement and construction technology, reasonable construction parameters were selected for the debris-lapping area of Shantiao tunnel and analyzed by using MIDAS-GTS finite element software. After grouting, the stability of the tunnel is well improved. For later engineering design and construction provides a reference.
