摘　　要：在寒区堤防工程中,对渗流现象进行充分的分析和了解,才能对堤防工程安全性进行有效管理和控制。基于Geo-Studio软件,对某寒区堤防工程进行模拟渗流试验,并结合有限差分法,模拟分析渗流影响。结果显示,凌汛期春汛水位最高流速约为1.94m/d,渗透流速由0.39m/d升至8.95m/d,梯度变化微小;非凌汛期特征水位渗透流速、梯度几乎在2以下,表明是否处于凌汛期对梯度影响较小,对渗透流速影响较大。研究方法对寒区堤防工程安全性管控具有一定的参考价值。In cold region embankment engineering,a thorough analysis and understanding of seepage phenomena is necessary to effectively manage and control the safety of embankment engineering.The study is based on Geo-studio software to conduct simulated seepage experiments on a embankment project in a cold region,and combines finite difference method to simulate and analyze the influence of seepage.The experiment shows that during the ice flood season,the highest flow velocity of the spring flood water level is about 1.94m/d,and the infiltration velocity increases from 0.39m/d to 8.95m/d,with small gradient changes.The characteristic water level infiltration velocity and gradient during non ice flood season are almost below 2.Whether it is in the ice flood season has little effect on the gradient,but has a significant impact on the infiltration velocity.It can be seen that the research method has certain reference value for the safety control of embankment engineering in cold regions.
