摘　　要：高填方地基受原始地基、填料、填筑施工工艺等影响,容易出现地基承载力不足、地基变形不收敛等情况,工后地基沉降计算亦缺乏完美的计算模型。通过实际工程案例,对高填方地基原始地基处理、填料控制、填筑的施工工艺进行分析研究,采用经验公式、数值模拟等手段对高填方工程沉降量进行计算,并与工后沉降监测数据进行了对比,对高填方地基的关键技术进行了总结分析,为类似项目提供了解决问题的思路和方法。Due to the influence of the original foundation,filler and fill construction technology,the high fill foundation is prone to insufficient bearing capacity and non-convergence of foundation deformation,and the settlement calculation of the foundation after construction lacks a perfect calculation model.Based on actual engineering cases,it analyzes and studies the treatment of the original foundation,the control of the fill and the construction technology of the filling of the high fill foundation,adopts the means of empirical formula and numerical simulation to calculate the settlement amount of the high fill project,and compares it with the post-construction settlement monitoring data,and summarizes and analyzes the key technologies of the high fill foundation.It provides the thought and method to solve the problem for similar projects.
