摘要
三台阶开挖法作为一种隧道施工工艺,由于其快速、操作简便等优点,在实际隧道工程中得到广泛应用。结合广州从化至清远连州高速公路项目中的元墩隧道工程,通过三台阶开挖法在实际隧道工程软弱围岩施工中的应用,阐述了其施工原理、施工工艺以及控制要点。
As a kind of tunnel construction technology,three-step excavation method has been widely used in practical tunnel engineering because of its advantages such as fast speed and easy operation.Combined with the Yuandun tunnel project of Guangzhou Conghua to Qingyuan expressway project,this paper expounds the construction principle,construction technology and control points through the application of three-step excavation method in the construction of soft surrounding rock in actual tunnel engineering.
