Abstract

复杂地质条件下的填埋场深部可能存在潜在的渗漏通道，为渗滤液向场外扩散提供途径，亟需建立基于三维的渗漏通道多场耦合渗流数值分析系统，阐明深层渗漏通道渗流形成机制，利用离散元法可以很好地解决这些非连续介质中的流固耦合问题。基于离散元法，提出了孔隙密度流法，该方法实现了非连续介质中的流固耦合和溶质运移模拟，通过模型箱、水力压裂、隧道注浆等数值模拟并与真实试验进行验证，证明了模型的可行性和准确性。基于上述的二维孔隙密度流法，进一步开发了三维的孔隙密度流法，该方法基于颗粒的位置对流体域进行划分和计算，实现三维空间中的流固耦合及溶质运移计算。进一步地，将该流固耦合方法用于污染物运移数值模拟，为探究复杂地质条件下污染物的运移规律提供了一种有效的途径。
