较高天然地下水位下渗控分析的边界处理方法

摘要

The recharge simulation method of intercepting certain boundary flow under higher natural water table is studied and presented．By introducing transition layer unit and in Combination with flow continuity condition，observing flow change in transition layer unit under effect of filtration drain system，the flow regulation at equivalent node of transition layer unit is set up to simulate estimating recharge analysis method of intercepting certain boundary flow with filtration drain system．%研究并提出了较高天然地下水位条件下截取边界定流量补给模拟方法。通过引进过渡层单元，并结合流量连续性条件，考察排渗系统作用下过渡层单元内流量的改变，建立了以过渡层单元等效节点流量调整，模拟有排渗系统截取边界定流量补给的计算分析方法。计算表明，该方法能较好地反映排水系统对截取边界水位的影响，并且有收敛速度快的特点。
