Analysis on the Main Urban Geological Environment Problems and Characteristics of Qingcheng District, Qingyuan City, Guangdong Province

随着清远市清城区城市建设的快速发展,城市地质环境问题日渐显露。依托清远市清城区城市地质调查工作,围绕清城区城市发展战略和亟待解决的城市地质环境问题,通过以往地质资料分析、地表综合调查和钻探等多种方法相结合,总结和梳理了清城区存在的主要地质环境问题,包括可溶岩与岩溶、地质灾害、富水砂砾层、巨厚风化壳、软土、矿山地质环境等。同时剖析了主要地质环境问题的分布范围、分布特征和对城市建设发展的影响,并提出相应的防治建议,为城市发展规划、建设、管理与防灾减灾提供基础数据和科学决策依据。

With the rapid development of urban construction in Qingcheng district of Qingyuan city, the ur-ban geological and environmental problems are becoming more and more obvious. Through the urban geological survey in Qingyuan city, based on the urban development strategy of Qingcheng District and the urban geological environment problems to be solved urgently, through the previous geological data analysis, comprehensive surface investigation and drilling methods, this paper summarizes and analyzes the main types of existing geological environment problems in Qingcheng district, they can be divided into six categories, which are geological disaster, soluble rock and karst, water-rich sand pebble layer, huge thick weathering crust, soft soil and mine geological environment problems. This paper analyzes the distribution range, distribution characteristics and influences on urban construction and development of these problems, and puts forward the corresponding prevention and treatment suggestions. It provides basic data and scientific decision basis for urban development planning, construction, management and disaster prevention and mitigation.
