1:50万比例尺的安徽省工程地质分区图是综合性工程地质图。编图目的是为本省在经济建设中的规划和布置各种类型建筑物提供工程地质依据。在图中分出了四级工程地质区:Ⅰ,区域;Ⅱ,地区;Ⅲ,区;Ⅳ,亚区。第Ⅰ级工程地质区——“区域”根据新构造运动和大地貌条件来划分;分出了基岩区域,过渡区域和堆积区域。第Ⅱ级工程地质区——“地区”是依据划分开不同的岩系组合而决定的。这样,在基岩区域中根据大地构造,在过渡区域根据基岩和表层沉积发育的不同情况,在堆积区域中按第四纪沉积物不同发育组合来划分。所分出的第Ⅰ、Ⅱ级工程地质区如下: Ⅰ、基岩区域: Ⅰ_1、江南台背斜地区; Ⅰ_2、下杨准池槽地区;
The 1: 500000 scale Anhui Provincial Engineering Geological Zoning map is a comprehensive engineering geological map. The purpose of the plan is to provide engineering geological basis for the planning and layout of various types of buildings in the province’s economic construction. Divided in the figure four engineering geological area: Ⅰ, area; Ⅱ, area; Ⅲ, area; Ⅳ, sub-area. Grade Ⅰ engineering geological area - “area” is divided according to neotectonic movement and large landform conditions; base rock area, transitional area and accumulation area are separated. Grade II engineering geological area - “area” is based on the division of different rock series determined. In this way, according to the tectonics in the bedrock area, the transitional area is divided according to different developmental assemblages of Quaternary sediments in the sedimentary area according to the different conditions of bedrock and surface sedimentation. The classified Ⅰ, Ⅱ engineering geological areas are as follows: Ⅰ, bedrock area: Ⅰ_1, Jiangnantai anticline area; Ⅰ_2, Yang quasi-tank area;
