中文摘要：

文章收集了自1995—2010年间宣城市重要工程中具有代表性的勘察项目77项,共998个钻孔资料。对其勘察项目中的钻孔资料进行分析、归纳、整理和汇编,并根据工程地质分区的基本原则,以地形地貌作为一级分类因素,对宣城市的工程地质进行了初步分区,同时归纳总结了各区的工程地质特征,为宣城市的未来城市建设提供勘察要点,避免勘察资源浪费,同时可以提高城市土地利用率。

英文摘要：

The data of 998 boreholes of 77 representative projects from important engineering survey projects in Xuancheng City between 1995 to 2010are collected.The analysis,induction,sorting and assembly of the borehole data of the survey projects are conducted.According to the basic principles of engineering geological division,topography is used as primary classification factor and the engineering geology of Xuancheng City is partitioned into several preliminary zones.The characteristics of the engineering geology of each zone are summarized.The study result can provide survey points for the future urban construction in Xuancheng City,avoid the survey resources waste and improve the utilization rate of urban land.
