摘　　要：当黏性土中水的渗流不符合Darcy定律时,传统的砂井固结理论已不再适用。这时,需要考虑非理想砂井的Hansbo渗流方程。为此提出基于Hansbo渗流法的砂井地基固结处理分析,基于Hansbo渗流的地基固化模型的建立,并使用有限差分法对渗流方程进行求解,探究砂井地基固结过程的影响因素,分析Hansbo渗流参数、地基厚度等的影响,验证其分析方法的正确性。When the seepage of water in viscous soil does not conform to Darcy's law,the traditional consolidation theory of sand well is no longer applicable.At this point,the Hansbo seepage equation for non-ideal sand wells needs to be considered.This paper puts forward the analysis of sand well foundation consolidation based on Hansbo seepage method,establishes the foundation curing model based on Hansbo seepage method,and uses the finite difference method to solve the seepage equation,and explores the influencing factors of sand well foundation consolidation process.The influence of flow parameters and foundation thickness of Hansbo is analyzed to verify the correctness of the analysis method.
