影响黄山市中心城区工程建设的地质因素及工程建设适宜性评价

通过野外地质调查和室内综合分析,研究黄山市中心城区地形地貌、水文、工程地质、水文地质和地质灾害等可能影响工程建设的主要地质因素的发育特征,并运用多因子分级加权指数法进行工程建设适宜性评价。研究区可划分为工程建设适宜区、较适宜区和适宜性差区3个等级;黄山市中心城区地质环境总体较好,工程建设适宜区和较适宜区面积广且成片分布,与定性认识基本吻合。以上认识可为黄山市中心城区城市规划布局、建设、发展及工程选址提供基础资料和决策依据。

Geological factors-based suitability evaluation for engineering construction in the urban area of Huangshan

Through field geological survey and comprehensive analysis,this paper investigated major geological factors which may influence urban engineering construction and their development characteristics.These factors include topography and geomorphology,hydrology,engineering geology,hydrogeology and geological hazard.Suitability for engineering construction was evaluated using multifactorial weighted index method.The study area can be divided into three suitable areas:well suitable,generally suitable and poorly suitable.The urban area in the city of Huangshan has favorable geo-environmental conditions,with the first two areas jointly distributed widely,and this is basically consistent with qualitative analysis results.The understanding above can provide basic information and decision-making basis for urban planning,construction,development and project location of the urban area of Huangshan.
