摘　　要：基于光纤光栅传感技术搭建了海洋平台变形检测实验系统,通过合理布置测点对导管架平台结构进行了静载变形检测实验,提出了利用桩腿应变总和与竖向静载的关系曲线对平台超载隐患进行安全预警的方法,旨在为国内类似平台的变形检测与长期监测研究提供借鉴和参考。A system of deformation detection for offshore platform is formed based on fiber-optical grating sensing technology, and the experiment of deformation detection under static loads is proceeded with reasonable arrangement of sensors on a jacket structure. Then the forewarning method of platform overload hazards is proposed by using the curve of the sum of leg strains vs the vertical static loads. The results can be referred during the deformation detection and constant monitoring of similar platforms in China.
