| 摘 要： | 针对铺设在滑坡体内的管道,提出了基于光纤光栅传感的管道滑坡监测方法。阐述了已知管道上三点应力求最大应力的方法。采用温度自补偿式光纤光栅应变传感器监测管体应力,对传感器测量的5.12汶川地震后管体应力数据进行分析。结果表明:地震对滑坡有显著影响,发生了浅层滑动面的较大位移;管体的应力都有显著增长,但总应力水平还低于预警阈值,尚处于安全状态。

| Abstract: | In view of pipelines laid in landslide mass,a security monitoring system is proposed.A method for evaluating maximum strain value based on strains of three points on the pipeline is presented.Temperature compensated FBG strain sensors are used in monitoring the strains of pipeline.The strain data of pipeline measured by sensors after 5.12 Wenchuan Earthquake is analyzed.The analysis results show that the earthquake has remarkable impact on landslide,which is proved by large displacement of shallow sliding p... |
