摘要
本文应用依相似理论设计模拟试验台,对积极冻结阶段及掘砌施工阶段中冻结管的受力与诸影响参数间的关系进行了模拟试验研究,得出了初步的变化规律,并探讨了冻结管断裂的原因。
According to the similitude principle the authors design a modelling test facility. The relation between the stress acting on freezing pipes and its influence factors during both ac-tive freezing and excavating periods are studied. The preliminary regularity of stress distri-bution is presented, and the breaking reasons of freezing pipes are also discussed.
