摘要
采用ANSYS软件 ,对竖井冻结壁交圈过程中的不同发展阶段和各种典型情况进行了数值建模和计算 .结果表明 ,随着冻结柱的逐渐增大 ,地下水渗流经过冻结柱时产生绕流 ,出现流速增大现象 ;而且在不同交圈过程中 ,流速增大的程度不同 .该研究为一些井筒的冻结壁交圈时间的延长原因分析提供了理论依据 ,同时对如何缩短积极冻结工期提供了方法 .
Numerical models were established to analyze the fluid flow in the aquastrata using ANSYS, which concerned some different developing stages and special scene when ice posts were developing to intersect each other in a shaft freezing. As the gaps are becoming smaller and smaller, the seepage velocity is increased, the high rate is related to the conjoining pattern of the ice post. It is why some shaft freezing time are delayed, and benifit to speed up the process of shaft ice wall.
