随着我国科学技术的不断发展和进步,我国的高速公路、高速铁路、城市轨道交通等得到迅速发展,隧道及地下工程越来越多。对于隧道建设而言,形成了多种设计理论和工法,如矿山法、掘进机法、明挖法、地下连续墙、盖挖法、浅埋暗挖法、盾构法、沉管法等,这些方法在隧道建设实践中发挥了十分重要的作用;但在具体实践中也出现了一些问题,尤其是一些坍方事故的发生,规模较大、造成了生命和财产损失、影响恶劣。这些事故的发生,血的教训,警示人们要高度关注和重视软弱围岩隧道的施工安全。故而在软弱围岩隧道施工时,通常需要根据软弱围岩的具体特征选择适合的施工技术,最优机械配置和科学的管理模式等方面的准备,提升软弱围岩的建筑质量和建筑安全。文章主要就软弱围岩隧道施工技术展开探究,以供参考。
With the continuous development and progress of science and technology in our country, China’s highways, high-speed railways and urban rail transit have witnessed rapid development with more and more tunnels and underground works. For the tunnel construction, a variety of design theories and methods have been formed, such as mining method, roadheader method, digging method, diaphragm wall, cover excavation method, shallow buried tunneling method, shield method, These methods have played a very important role in the practice of tunnel construction. However, some problems have appeared in the practice, especially the occurrence of some landslide accidents. The large scale causes the loss of life and property and the bad influence. The occurrence of these accidents, the lesson of blood, warn people to pay close attention to and pay attention to the construction safety of soft rock tunnels. Therefore, in the construction of soft surrounding rock tunnels, it is usually necessary to select the appropriate construction technology, optimal mechanical configuration and scientific management mode according to the specific characteristics of soft surrounding rock to improve the construction quality and safety of weak surrounding rock. The article mainly explores the construction technology of soft surrounding rock tunnel for reference.
