油气输送管道河流穿越管段常年受到水流冲刷、采沙等活动、外部物体撞击、水底土壤腐蚀等外部条件的作用,相比于陆地管道存在更高的安全风险。为保证油气管道运行的安全性,针对河流穿越管段最大埋深普遍在5m以上,最大甚至超过40m的特点,目前一般采用基于单次动态校准的绝对电磁法对穿越管段敷设状态进行定期检测。然而,在长期使用中发现,当管道最大深度超过20m后,检测准确度快速下降,逐渐达到不可接受状态,因此,在中,研究提出了一种基于多次校准的现场检测方法,根据现场试验结果,采用该方法可有效降低绝对电磁法检测穿越管段敷设状态的误差。

本文利用中国国家台网在青藏地区布设的台站记录到的近5年震级在5.8以上、震中距在东经88°~120°之间的39个远震地震事件进行SKS横波分裂测量,来研究青藏高原及其周缘地区的各向异性及变形特征。在青藏内部地区,SKS横波分裂测量的快轴自西向东逐渐从NE—SW向转为E—W向,再转为NNE向,与GPS速度场方向基本一致,呈顺时针方向变化。造成此地区SKS分裂测量结果的原因可能为缅甸板块向东俯冲时发生向西的后撤运动,使得此区域的岩石圈产生环状变形。川滇地区南部的GPS数据显示了近ES向的地表形变且走滑断层走向为NW—SE向,Pms地壳各向异性快轴方向主要为S—N向或NNE—SSW向,SKS分裂结果揭示了E—W向的上地幔各向异性特征,与Pms快轴方向以大角度相交或垂直,说明云南地区深部软流圈地幔流动场与地壳及地表变形特征不一致,地幔和地壳的变形机制和各向异性来源不同,发生解耦变形。
