浅层穿越水库隧道施工技术及围岩稳定性探索

Exploration on Tunnel Construction Technology and Surrounding Rock Stability of Shallow Crossing Reservoir

水库隧道施工中,围岩条件较为复杂,易出现围岩失稳事故,会带来重大经济损失。水库隧道是常见的地下工程,围岩的稳定性与施工技术有很密切的联系,设计和施工中需要对隧道围岩的稳定性加以评价。论文主要分析了浅层穿越水库隧道施工技术,并根据围岩稳定性,分析其影响因素,探讨了施工技术方法。

In the construction of the reservoir tunnel, the surrounding rock condition is more complex, and the instability accident of the surrounding rock is easy to occur, which will bring great economic loss. Reservoir tunnel is a common underground engineering. The stability of surrounding rock is closely related to the construction technology. It is necessary to evaluate the stability of surrounding rock in design and construction. This paper mainly analyzes the construction technology of shallow tunnel through reservoir, analyzes the influencing factors and discusses the construction technology method according to the stability of surrounding rock.
