长距离深埋隧洞TBM拆机研究

Research on Dismantling of TBM in Long-Distance and Deep-Buried Tunnel

摘要: 本文结合新疆某隧洞工程施工实例，对长距离深埋隧洞TBM拆机方案提出了拆卸洞室前置法与“拆 + 埋”法，从地质、工程安全、投资、工期进行分析研究，最终采用“拆 + 埋”法实现TBM拆机，以期对长距离深埋隧洞TBM拆机施工提供借鉴，从而达到快速、安全、经济的目的。

Abstract: Based on a construction example of a tunnel project in Xinjiang, this paper proposes the pre-demolition method and the “demolition + burying” method for the TBM dismantling plan of a long-distance deep-buried tunnel. The analysis and research are carried out from the perspective of geology, engineering safety, investment, and construction period. Finally, the “dismantling + burying” method is adopted to realize the TBM dismantling, in order to provide a reference for the TBM dismantling construction of long-distance deep-buried tunnels, so as to achieve the purpose of rapid, safe and economical.
