有关隧道工程施工超挖的预防与控制的分析

摘要

In the new period, the construction technology and technological level of tunnel engineering in China has greatly improved, greatly improved the status of the tunnel constructi-on, building many good performance of the tunnel for the dev-elopment of the country. However, the phenomenon of overbr-eak stil serious in tunneling current, become the main factor a-ffecting the safety accidents evoked quality, tunnel, must be s-olved effectively. The paper taking the overbreak phenomenon of tunnel as the theme, through the analysis of induced factors of overbreak phenomenon, talked about the prevention and co-ntrol ing measures of overbreak phenomenon.%　　新时期，我国隧道工程的施工技术与工艺水平实现了大幅度的提升，极大地改进了隧道工程的建设状况，为国家发展建造了诸多良好性能的隧道。但是，超挖现象在当前的隧道施工中依然较为严重，成为影响隧道质量、诱发安全事故的主要因素，必须得到有效地解决。本文以隧道的超挖现象为主题，通过分析诱发超挖现象的因素，谈论了对超挖现象进行预防及控制的具体措施。
