摘要
从冻结工法施工仿真模型中温度场与应力场的交替及耦合条件下不同的时间相似常数问题出发,用相似转换法分别讨论了动应力场和温度场状态下的时间相似常数问题,并用两场耦合方程和冻土壁的蠕变方程导出了不同的时间相似常数,结合冻结工法的工程实际,提出了不同工况条件下模型应采用的时间相似常数,为这类试验模型的设计及试验控制提供了有价值的时间参量取值原则。
According to the alternation and coupling of the temperature and dynamical field at a freezing constructional similative model, the time similar constants are discussed in dynamical stress field and temperature field conditions are discussed, at the same time, on the basis of the coupling equation of those two fields and the creep equation about the freezing soil wall, other time similar constants are presented. Some kinds of time similar constants are put forward for different technological processes by a similative shifting method. Some valuable choosing principles of the time parameters are suggested for the test design and control of this kind of model.
