随着我国经济和社会发展速度加快,社会对于公共设施的需求越来越高,而公路长隧道作为保证社会交通的重要社会设施,其在我国逐渐开始进行了大量的隧道建设。公路长隧道施工要求较多,需要运用到较多的施工技术和施工材料,且其的施工质量对于社会的影响非常大。因此为了保证城市能够进行快速的建设,市政工程能够以高标准的质量满足社会发展需求,需要对公路长隧道施工开挖的支护难点进行相关的分析,以了解公路隧道施工方面的技术,使得其能够合理的对施工难点进行相关的解决。针对此本文主要详细阐述了公路长隧道施工的施工技术,以及对其开挖时的支护难点进行了相关的分析,并同时提出了利于提高公路隧道施工质量的处理对策。
With the rapid economic and social development in our country, the demand for public facilities is getting higher and higher. As a major social facility to ensure social traffic, the long tunnel has gradually begun to carry out a large number of tunnel construction in our country. Long tunnel construction requirements are more, need to apply more construction technology and construction materials, and the construction quality of its impact on society is very large. Therefore, in order to ensure rapid urban construction, municipal engineering can meet the needs of social development with a high standard of quality. It is necessary to analyze the supporting difficulties in construction of long tunnels in order to understand the technology of highway tunnel construction so that It can reasonably solve the construction difficulties. In this paper, we mainly elaborate the construction technology of the long highway tunnel construction, as well as the related difficulties in the support of the excavation. At the same time, we put forward some countermeasures to improve the construction quality of the highway tunnel.
