Research Of Engineering Geology Division Along The Yangtze River In Anhui Province And Electronic Map-making

Anhui Province along the Yangtze River engineering geology division characteristics can provide theoretical guidance and technical support for the port construction in the coastal area of the Yangtze River, in a certain extent solve the port construction due to the engineering geological conditions are very complicated in construction cost this problem has important economic significance and can produce good economic benefit and social benefit. From the point of view of major domestic and foreign urban engineering geological study, based on a large amount of drilling data and seismic geological environment analysis and engineering geological zoning research in, there are important social and economic significance.Based on the engineering geology along the Yangtze River region as a research object, take research methods of data collection, scene investigation, laboratory test, theoretical analysis and numerical simulation, partitioning along the coastal areas along the Yangtze River in Anhui Province, and combined with the type of project construction, engineering geological zoning evaluation, Yangtze River coast engineering geological zoning map making. Using GIS software of original geological map, detailed description of the complete Yangtze River coast electronic map, and secondary development of the electronic map, data import map to show it. The main results and conclusions are as follows:(1)Along the coastal areas along the Yangtze River in Anhui Province in accordance with the principle of engineering geological zoning can be divided into 3 engineering geological zones:exposed bedrock-low mountain and hilly area, terrace plain hard soil, and floodplain-Jiangxin Island in soft soil area; (2) the seven engineering geological sub areas:magmatic rock distribution sub Zone, sedimentary rock distribution sub district, Jiangxin Island sub district, sub district level terrace, sub district, the second terrace and alluvial plain subregion product, floodplain sub region; (3)There are 21 engineering geological area in each sub region:Magpie Jiang Zhu Dun Cun landslide area, San shan District Dong Gang group collapse District, Changsha Xiang-Feng Yi Xiang piping District, old Zhou Xiang bank collapse area.
