摘要
详细介绍了对某工程发生变形的大口径埋地钢管进行现场变形测量及回填土取样试验等工作。对埋地钢管的工作原理进行了分析并且应用Spangler-lowa公式进行变形量模拟计算,阐明了该工程钢管变形的主要原因,并提出了钢管变形预防措施。
The deformation field measurement and backfilled soil sampling test of the deformed buried steel pipe with large diameter for a projet are introduced in this paper.Buried steel pipe working principle is analyzed and the deformation amount is calculated by＂ Spangler-lowa＂model.The main reason of the buried steel pipe deformation is explained clearly ,and the prevention and control measures are introduced simply.
