水电站建设施工中隧洞开挖是极为关键的环节,要保证隧洞开挖过程中施工区域围岩结构的稳定性,避免安全事故的发生,就必须要认真做好支护措施,管棚法属于一种超前支护的有效方法,其在水电站隧洞开挖施工中能够发挥出良好的效果。为了更好的了解和运用管棚法,保证隧洞开挖支护的安全性,文章针对管棚法在水电站隧洞开挖与支护施工中的应用要点进行讨论。 In excavation and construction of a hydropower station, tunnel excavation is an extremely crucial link. To ensure the stability of the surrounding rock structure in the construction area during tunnel excavation and to avoid the occurrence of a safety accident, support measures must be conscientiously implemented. The pipe shed method belongs to one An effective method of advanced support, which can play a good effect in the tunnel excavation construction of hydropower station. In order to better understand and use the pipe shed method to ensure the safety of tunnel excavation and support, the article discusses the application of pipe shed method in the tunnel excavation and support construction of hydropower station.
