摘要
台阶法施工技术是一种有效防治围岩失稳的方法,在公路隧道项目中有广泛的应用前景。文章以加禄隧道为例,探讨了台阶法施工技术在公路隧道项目中的应用。研究结果表明,台阶法施工技术在加禄隧道项目中得到了成功应用,通过逐级建造台阶,能有效应对复杂的地质条件和地形起伏,降低围岩失稳的风险,并提高施工的安全性和效率。
Benching tunneling method construction technology is an effective method to prevent and control the instability of surrounding rocks,which has a wide application prospect in highway tunnel project.Taking Jialu tunnel as an example,this paper discusses the application of benching tunneling method construction technology in highway tunnel project.The research results show that the benching tunneling method construction technology has been successfully applied in Jialu tunnel project.By constructing benches step by step,it can effectively deal with complex geological conditions and topographic fluctuations,reduce the risk of surrounding rock instability,and improve the safety and efficiency of construction.
