近年来，随着人工冻结法凿井深度的增加，冻结管断管事故时有发生，给深部冻结工程带来巨大经济损失，因此有必要对冻结管及其接头在低温条件下的力学性能进行实验研究。论文对3组共12根冻结管进行了低温条件下的力学特性实验(每组三根对接冻结管，一根无焊接接头的冻结管)

In recent years,with the increase of the artificial freezing method sinking depth,the freezing pipe broken accidents have occurred.This bring huge economic loss to the deep freeze engineering.So it is necessary to investigate experimentally for the freezing pipe and the mechanical properties of the joints under low temperature conditions.In this paper,3 groups of 1 2 roots of freezing pipe were investigated under low temperature condition (there are three docking freezing pipes and a no welding joints freezing pipe in each group).
