钢质输油管道浅埋的处理方法

由于自然或人为因素的影响，造成埋地管道覆土不足，基于裸露，危及管道的安全运行。为此，提出了处理方法，比较了修筑管堤和沉管两种处理方法的优缺点。并对沉管法在施工设计中的允许跨度、弹性曲率半径、伸长量及最小开挖长度等要素作了介绍，同时指出了施工中的具体要求和注意事项。

Techniques for Correcting Inadequately Buried Steel Pipelines.

Pipeline with inadequate or even no depth of cover may result from either natural or human causes, endangering the normal operation of pipeline. Introduced are two corrective methods, namely construction of pipe embankment and pipe lowering, with their strong and weak points discussed. Also given for the pipe lowering method are the allowable span,elastic radius of curvature , elongation and minimum excavation length > with the construction requirements and points needing for attention proposed.
