谈长大隧道的施工技术

摘要

隧道建设伴随着我国铁路和高速公路的迅猛发展及业主对安全、质量、工期的要求越来越高正逐渐朝向长、大、深的方向发展。而长大隧道在工程中往往起着工期控制的作用，为此寻求长大隧道安全、快速施工的有效方法是必要的，本文结合山西省西山隧道的施工对长大隧道的施工技术进行了介绍。%　　With the rapid development of Chinese railways and highways, the demand for safety, quality and schedule of tunnel construction is higher. The tunnel is longer, larger and deeper. It is necessary to find the safe rapid construction method of long and large tunnel. Combined with the construction of Shanxi Xishan Tunnel, the paper describes the construction technology of long and large tunnel.
