| 摘 要： | 渤海某平台为了防止打井作业期间上部荷载过大,需要在一年周期内对上部荷载变化进行全程监控.光纤光栅应变计的高灵敏度与长期稳定性,适合结构物应变长期监测.利用在平台组块支撑部位粘贴光纤光栅应变计,有效地监测平台上部荷载变化信息,保障平台打井作业正常运行.并对光纤应变计进行长期监测中存在的问题进行讨论.

| Abstract: | Monitoring the status of topside mass during a whole year is needed so as to avoid the excessive mass of the platform.Fiber Bragg Grating sensors have high sensibility and long-term reliability,which are very suitable for monitoring the safety of structures in complex environment.FBG sensors were installed on the bearing parts to monitor the variety of the upper load of the platform effectively.Problems which occurred in the monitoring are discussed in the paper. |
