摘　　要：以郑州市郑东新区邮政大楼地下室深基坑工程为例,建立Verhulst模型,借助MATLAB软件的数值计算、绘图功能,对深基坑坑周土体水平位移量进行预测,并将该预测结果与GM(1,1)模型预测结果及实测数据进行对比分析.结果表明,Verhulst模型预测精度达到了一级,优于传统的GM(1,1)模型,对于预测类似基坑工程水平位移量有借鉴作用.Taking the basement deep foundation pit of the post office building in Zhengdong New District for an example, a Verhulst model is built, and by MATLAB software with the functions of numerical calculation and drawing, the horizontal displacement of the soil around the deep foundation pit is predicted. Then, the predicted results are compared with those predicted by GM （ 1, 1 ） model predictions and experimental data. The results show the prediction accuracy of Verhulst model is higher than that of GM （ 1, 1 ） model. This can provide a reference for horizontal displacement prediction of similar foundation pit engineering.
