冻结管断裂能量分析

In this paper the author got the inner stress from brine and frozen earth, and got the vertical stress occurring from the relative displacement of freezing pipe and surrounding frozen earth, and then derived the fracture energy level when the freezing pipe was breakdown, within summarizing the characteristics of the working freezing pipe. By the energy conservation, most of the energy converted into shock. If we can get this energy signal, we can obtain the position of fracture freezing pipe through the energy analysis. There was a guidance significance for fracture repairing.
