摘　　要：结合广州220 kV厚德变电站明挖段电缆隧道施工安全监测实例,系统地介绍钢板桩加钢支撑支护体系中施工安全监测设计、监测仪器设备的安放、隧道明挖法施工过程的实时监测频率、监测警戒值确定及监测报告等内容。并介绍一种新的监测方案在特殊施工场地的应用,根据现场实时监测数据,特别是异常数据的分析及安全预测,针对其结果采取相应的处理措施,避免了工程事故的发生,确保了施工现场和周围环境的安全。Combined with the monitoring example of the open-cut section of a cable tunnel for Houde Substation in Guangzhou,the monitoring safety design and instrument layout were introduced in the system of steel sheet pile and steel struts structure . The monitoring frequency, alertness values and reports etc were presented. According to the analysis and forecast of monitoring data especially the unusual ones, monitoring result was researched to adopt countermeasures, and safety precautions were adopted in time, hence the safety of the field and environment could be ensured.
