摘　　要：为探究渗流条件下人工冻结装置冻结管排布方式对温度场的影响,文章设置三种方案进行对比,通过有限元软件进行分析。研究表明,由于渗流作用的影响,冻结装置形成的冻土帷幕呈现上游窄下游宽的现象;沿渗流方向上的冻土帷幕发展并不受冻结管排布方式的影响,冻结结束后最终温度基本一致;冻土帷幕的冻结深度与冻结管长度基本一致。In order to explore the effect of the layout of freezing pipes in artificial freezing devices under seepage conditions on the temperature field,this paper compares three schemes and analyzes them by using finite element software.According to research,due to the influence of seepage,the frozen soil curtain formed by the freezing device exhibits a phenomenon of narrow upstream and wide downstream;the development of frozen soil curtain along the direction of seepage is not aff ected by the layout of freezing pipes,and the final temperature is basically the same after freezing;the freezing depth of the frozen soil curtain is basically the same as the length of the freezing pipe.
