隧道围岩坍塌原因分析及有效的综合处理技术

Cause Analysis on the Overbreak of Tunnel Surrounding Rocks and the Effective Comprehensive Treatment Technology

随着铁路、公路建设的迅速发展,越来越多的隧道穿越于地质条件复杂地区,在各种不利因素的共同影响作下,隧道出现塌方现象日趋增加,给隧道的施工安全、质量及进度带来极大影响。所以我们在采取措施努力避免隧道塌方的同时,也必须提高隧道塌方后的处理技术及措施方面的应对能力,使已发生事故造成的各方面影响降至最低。笔者基于新关坡隧道塌方处理实例,对于隧道产生塌方的原因进行分析,制定有效的隧道塌方处理措施,与同行进行探讨,共同提高。

With the rapid development of railway and highway construction, more and more tunnels cross the areas with complex geological conditions. Under the influence of adverse factors, the phenomenon of tunnel overbreak is gradually increasing, which brings great influence to the safety, quality and progress of tunnel construction. So, this paper takes measures to try to avoid the tunnel overbreak, at the same time, it also improves the response capacity of management technologies and measures after the tunnel overbreak to make all aspects of influence caused by the accident has happened increase to the lowest. Based on the process instance of the tunnel overbreak in Xinguan slope, the author analyzes the causes of tunnel overbreak, makes the effective treatment measures of tunnel overbreak to discuss these with counterparts and improve together.
