观音山隧道塌方段施工处理方法

The Construction Handle of Landslide in Guanyin Mountain Tunnel

由于未采用新奥法原理指导施工、监控量测工作不到位、采取的施工方法不当以及施工过程中的不规范行为等原因,造成了观音山隧道塌方。根据处理观音山隧道坍方的工程实践,论述了公路软弱围岩段隧道施工应尽早封闭成环、重视监控量测工作、加强施工管理的重要性,对同类围岩隧道施工具有一定的借鉴意义。

Because of not using NATM principle instruction construction, control and measurement work if no enough,the construction method of adopt isfft appropriate, construction process of not norm behavior, according conduced landslide of the Guanyin mountain tunnel, it discussed the significance in highway weak rock segment tunnel about as early as possible close into wreath , regard monitoring and measurement work, strengthen a construction management, it is have reference value to similar construction.
