文摘Using the simulation test facility designed on the basis of similitude principle, the authors of the paper carry out a series of simulation tests and study the influence of effective factors on the stress in the freezing pipes during hoth periods of active freezing and excavating-lining. They obtain preliminarily the regularity of stress variation and discuss the causes of freezing pipe fracture.
