地下洞室群数字信息化智慧监测及预警技术应用

Application of Digital Information Intelligent Monitoring and Early Warning Technology in Underground Cavern Group of Lianghekou Hydropower Station

水电站地下洞室群施工已成为当今地下工程中最复杂的系统工程,是地下工程结构建造技术的最高集成。根据两河口水电站工程实际,在三维设计的基础上,通过引入BIM思想,综合洞室群地质、进度、监测、数值仿真、安全评价等信息,建立地下洞室群三维全尺度动态安全信息模型,并以此为基础研发地下厂房洞室群围岩稳定动态反馈分析和安全预警系统,实现数字信息化智慧监测及预警。

The underground cavern group construction of hydropower station has become the most complex system engineering in the underground engineering,which is the highest integration of the underground engineering structure construction technology.Based on the practice of Lianghekou Hydropower Station and the three-dimensional design,this paper mainly introduces the idea of BIM,which integrates the geological,progress,monitoring,numerical simulation,safety evaluation and other information of the underground cavern group,establishes the three-dimensional full-scale dynamic safety information model of the underground cavern group.The dynamic feedback analysis and safety early warning system for surrounding rock stability of underground powerhouse caverns are developed to realize intelligent monitoring and early warning of digital information.
