摘　　要：海南五指山形变台洞体内潮湿的环境对仪器影响巨大,对传感器、标定系统和数据传输线路都有不同程度的破坏导致设备故障高发,影响观测数据质量和连续率。对五指山形变台观测设备的墩体内外做防潮处理,结果显示在设备各个关键部件,如墩体、探头、连接部位及主机做防潮控温或控压试验,可以有效减少外界因素对仪器的影响,提高数据运行率和有效率。防潮处理后,仪器的背景噪声也有明显的下降,水管倾斜仪平均噪声水平从改造前的0.233下降到改造后的0.147;增加防潮盒的密度有利于降低洞体内相对湿度:放置25盒防潮盒在三套设备的墩体上,记录到相对湿度从97%RH下降到92%RH,放置100个防潮盒在三套设备的墩体上,记录到相对湿度下降到80%RH以下。The humid environment inside the cave at the Five-Finger Mountain deformation station in Hainan has a significant impact on instruments,which caused different degrees of damage to sensors,calibration systems,and data transmission lines.The aforementioned environment could result in frequent equipment failure,which affects the quality and continuity of observation data.In this study,moisture-proof technique was applied to the equipment inside and outside the cave at the Five-Finger Mountain deformation station.Based on the performance and working principle of the instruments,moisture-proof and temperature or pressure control tests were conducted on various key components of the equipment(e.g.the pier,probe,connection parts,and mainframe),which effectively reduced the impact of external factors on the instruments and improved data uptime and efficiency.After the moisture-proof treatment,the background noise of the instruments also decreased significantly.The average noise level of the water pipe inclinometer decreased from 0.233 to 0.147 after the treatment.Increasing the density of the moisture-proof boxes is helpful for reducing the humidity inside the cave.Placing 25 moisture-proof boxes on the piers of three sets of equipment recorded a decrease in humidity from 97%RH to 92%RH,whereas placing 100 moisture-proof boxes on the piers of three sets of equipment recorded a decrease in humidity to below 80%RH.
