冻结管常温和低温力学性能试验研究

Experimental Study of Mechanical Characteristics of Frozen Steel Pipe Under Normal Temperature and Low Temperature

随着井筒人工冻结法凿井深度的增加,用于输送盐水的冻结管断管事故时有发生。为了保证人工冻结法施工工程的安全,需要对冻结管及其接头部位在常温和低温条件下的力学特性开展试验研究。

With the increased depth of shaft constructed by frozen method, the accidents of fracture of frozen steel pipe transporting cold water frequently happens. In order to ensure safety of man - made shaft constructed by frozen method, mechanical characteristics study of frozen steel pipe and connective position between steel pipes are researched under normal temperature and low temperature.
