黄土区浅埋偏压隧道进洞施工技术

Construction technology of shallow buried bias tunnel in loess area

以实际工程为例,针对黄土区的浅埋偏压隧道进洞施工展开探讨,提出超前长管棚搭设与地表锚杆支护等环节的关键技术。实际结果表明,提出的技术具有适用性,应用效果良好,可为进洞施工创设安全的环境,具有一定的参考价值。

Taking the actual project as an example, this paper discusses the construction of shallow buried bias tunnel in loess area, and puts forward the key technologies such as the construction of advanced long pipe shed and ground bolt support. The practical results show that the proposed technology is applicable and has a good application effect.
