谈软弱围岩铁路隧道开挖安全施工技术

Discussion on the Construction Technology of safe Excavation of Soft Surrounding Rock Tunnel

以某隧道工程为例,分析该工程施工的主要特点,围绕软弱围岩铁路隧道开挖施工,采取了完善超前地质预报工作和监控测量技术、合理优化开挖技术方案、严格控制每循环开挖进尺等措施,保证了施工的安全性。

Taking a tunnel project as an example,this paper analyzes the main characteristics of the construction of the project.In order to ensure the safety of construction,measures have been taken to ensure the safety of construction,such as improving geological forecasting in advance,reasonable optimizing excavation technology program and strictly control the excavation footage of each cycle.
