摘要
根据相似理论，首次建立了模拟大流水条件下土层液氮冻结的试验系统．本文详细介绍了试验系统的设计，并对冻结试验规律进行了分析和研究．
According to the theory of similitude,a Liquid Nitrogen Freezing(LNF)model testing system for soil under water flowing at a great rate is established for the first time.The design of the similitude model testing are detailly described and the freezing law is also studied in this paper.The influences of water flowing at a great rate on ground LNF is explored.
