支护预警系统在白鹤滩水电站地下工程开挖中的应用

Application of supporting early warning system to excavation of underground works in Baihetan Hydropower Station

由于白鹤滩水电站所处地形和地质条件的复杂性、多样性,导致白鹤滩水电站地下厂房开挖过程中存在较大的安全风险。为提高白鹤滩水电站地下工程开挖施工的安全性,针对地下洞室支护施工自主开发了支护预警系统,该系统加强了地下洞室支护施工的及时性和准确性,有效提高了白鹤滩水电站地下工程的安全性。在支护预警系统指导下,工程处于受控状态,效果良好。

Due to the complexity and diversity of the topographical and geological conditions of the site for Baihetan Hydropower Station,larger safety risk is there during the excavation of the underground powerhouse of it In order to enhance the safety for the excavation of the underground works of the hydropower station,a supporting early warning system is self-developed for the supporting construction of the underground tunnels and cambers therein.Thus,the promptness and accuracy of the supporting construction for the underground tunnels and chambers are strengthened by this system,and then the safety of the underground works of the hydropower station is effectively enhanced as well.Under the guidance of this system,the construction of the project is in a controlled condition all along with a better effect.
