对于隧道而言,其作为公路工程建设的一个重要部分,因受地应力、地下水以及地质断层和各种人工操作因素的影响,施工难度非常的大。尤其是公路隧道软弱围岩初期支护施工过程中,因隧道所处地质条件、围岩稳定性不同,所以实际施工过程中所采取的初期支护技术、开挖方式也存在着较大的差异性。以中兴隧道软弱围岩初期支护施工为例,对新奥法在此工程中的应用进行探讨,并在此基础上提出一些就洞口开挖、支护以及防水处理技术,谈一下自己的观点和认识,以供参考。
As for the tunnel, as an important part of highway construction, due to the stress of ground, groundwater and geological faults and a variety of artificial factors, the construction is very difficult. Especially in the initial support construction of soft surrounding rock of highway tunnel, the initial support technology and excavation method adopted in the actual construction process are quite different because of the geological conditions of the tunnel and the stability of the surrounding rock. Sex. Taking the initial support construction of soft surrounding rock in ZTE tunnel as an example, this paper discusses the application of the new Austrian law in this project, and on this basis puts forward some suggestions on how to excavate, support and waterproof the tunnels. And understanding, for reference.
