摘　　要：针对软土层空间分布不均、厚度差异大的大面积地基处理场地,利用Civil 3D软件建立场地三维地质模型,并绘制场地软土厚度等值线图,直观地反映了软土层在空间上的分布规律。结合不同软土厚度的典型钻孔沉降计算结果,软土层分别采用不插板不堆载、插板不堆载、插板堆载3种地基处理方案,兼顾了处理效果和工程造价。此外,利用Civil 3D软件建立堆载实体模型,用于计算堆载、卸载工程量,计算结果更加精细、准确,解决了传统断面法在交叉部位精度差、计算过程复杂等工程量计算问题。该实例可为后续自动化集装箱码头陆域开展地基处理精细化设计提供参考。For large-area foundation treatment sites with uneven spatial distribution of soft soil layers and large thickness differences,3D geological model has been built and contour map of the soft soil thickness has been drawn by Civil 3D,which is a more intuitive way to display the distributions of the soft soils.According to the settlement calculation results of typical borehole with different soft soil thickness,and giving consideration to both treatment effect and construction cost,three different foundation treatment schemes have been adopted for the soft soils of different thickness:no plug-in board and no piling,plug-in board without piling,plug-in board and piling.In addition,the software Civil 3D is used to calculate the quantities of surcharge preloading material and realize the refinement of the ground treatment process through 3D modeling,which can effectively overcome the shortcomings of large computation and insufficient calculation accuracy of the method of section.It is a reference for the fine design of foundation treatment for the land-forming project of the automated container stack yard.
