Analyzing the model, especially the activity of Taihang Mountain piedmont fault, we got such main conclusion:1. Based on sequence stratigraphy, the strata is divided from the selected drills. And the Quaternary stratigraphic framework of Handan city is established, dividing the Quaternary strata into four parts- Qh, Qp3O , Qp2Y and Qp1G.2. With all the selected drill data of Handan city, a drill database is established. A quaternary strata 3D model of Handan city is imitated by GOCAD and ArcGIS, and so are the bottom structural map of each horizon.3. Analyzing the 3D model and the contradistinction section of drills, we got: the stratum of Qh and Qp3 is smooth and flat, with a feature of a higher west, little difference between south and north and undistinctness of faults; there are several depocenters along S-N and N-W in the stratum of Qp2, and the evolution of the stratum is controlled by a couple of ruptures, which means the tectonic movement is active in this period of time.4. Since quaternary, main tectonic movements happened in Qp2 and have been stable in Qp3 and Qh.

获得主要结论如下：1、利用层序地层学的方法将收集的邯郸市钻孔以及论文所依托项目野外施工的钻孔进行了具体的地层划分与对比，建立了邯郸市第四系等时地层格架，将邯郸市第四系划分为全新统、更新统上部欧庄组(Qp3O)、更新统中部杨柳青组(Qp2Y)和更新统下部固安组(Qp1G)。2、利用收集到的邯郸市水文、工勘钻孔以及所依托项目初勘和详勘两个阶段野外施工的钻孔数据，建立钻孔数据库，通过使用三维建模软件GOCAD和地理信息系统软件ArcGIS等进行模拟，得到邯郸市市区部分第四系地层三维可视化模型，并获得各个地层的底部构造图；3、通过对所天生模型和钻孔廊带对比剖面的分析，可以得到：全新世和更新世晚期(Qp3)时期地形整体较平缓，整体上显示西高东低、南北差异不大的格式，断裂显示不明显；更新世中期(Qp2)时期沿南北向和北西向存在几个沉积中心，地层发育受几条断裂的控制，反映了研究区的构造活动在更新世中期较为活跃；4、邯郸市自第四系以来，主要构造运动均发生于更新世中期，到更新世晚期及全新世时期逐渐趋于稳定，进而使更新统上部和全新统地层沉积均一且完好。
