摘要
聚乙烯管材具有许多突出的优点,但这类管道与金属管道相比,其刚度普遍偏小,属于柔性管,在承受上部填土荷载及车辆荷载时,变形相对较大。本文针对管道的变形检测,介绍国内外目前常用和最新的几种检测技术,并对各自的检测原理、方法和各自特点进行了叙述,为进一步深入开展埋地聚乙烯管道变形检测技术与方法研究提供参考。
Buried polyethylene pipeline usually have a deformation when beating the weight of soil or vehicle due to its less rigidity compared with metal pipeline. This paper introduced some instructing buried-pipeline methods including their principles and features respectively.
