隧道超欠挖成因及其控制技术分析

Analysis of Causes of Tunnel Overbreaking and Its Control Techniques

本文主要分析了隧道超欠挖的基本情况,重点介绍了隧道超欠挖的成因,并制定针对性的控制技术,其不仅可以确保开挖各个工序的有效衔接,而且还可以有效降低超挖现象的发生,确保隧道工程施工的顺利进行。通过对隧道超欠挖成因及其控制技术进行分析,以此为隧道工程施工提供可靠的保障,从而实现经济效益和社会效益的最大化。

This paper mainly analyzes the basic situation of over - underbreaking tunnels, highlights the causes of over - underbreaking of tunnels, and develops targeted control techniques. It not only ensures the effective connection of various excavation processes, but also can effectively reduce over- excavation. The occmTence of the phenomenon ensures the smooth construction of the tunnel project. The analysis of the causes of tunnel overbreak and underbreak and its control technology are carried out to provide a reliable guarantee for the construction of the tunnel, so as to maximize the economic and social benefits.
