摘　　要：为探究氯气在地质构造中的赋存特征及其综合控制技术,文章以滇中引水工程狮子山隧洞为例,通过现场勘察和实测对氯气分布特征进行分析,提出以人工检测和自动监测相结合的方法对狮子山隧洞的氯气进行实时监控。实践证明:现场采用的智能化隧洞安全监控系统、专项超前预测预报、喷雾洒水、湿式凿岩和加强通风等措施能有效保证施工的安全。Shizishan Tunnel in the Central Yunnan Water Diversion Project is adopted as an example in the paper in order to explore the occurrence characteristics and comprehensive control technology of chlorine in the geological structure.The distribution characteristics of chlorine gas is analyzed through field investigation and actual measurement.A method combining manual detection and automatic monitoring is proposed to carry out real-time monitoring of chlorine in Shizishan Tunnel.The practice has proved that the safety of construction can be effectively ensured by the intelligent tunnel safety monitoring system,special advance forecast,spray sprinkling,wet drilling and strengthening ventilation measures adopted in the field.
