公路是国民经济的重要命脉,由于其特有的灵活性和优越性,发挥着其他运输方式不可替代的作用;公路隧道是公路工程结构的重要组成部分之一,随着我国社会主义市场经济的发展,西部大开发战略的实施,高等级公路已从沿海地区向西南西北山岭区延伸,公路隧道建筑规模也越来越大对公路隧道施工技术也要求越来越高。
Because of its unique flexibility and superiority, the highway plays an irreplaceable role in other transportation modes. The highway tunnel is one of the important components of highway engineering structure. With the development of socialist market economy in our country, The implementation of the strategy for developing the western region has led to the high-grade highways extending from the coastal areas to the mountainous areas in the southwestern, northwestern and northwestern regions. The construction scale of highway tunnels is also growing, and the construction technology of highway tunnels is also demanding higher and higher.
