关中城市群城市建设工程地质分区与适宜性评价——以西安灞桥南部地区为例
|
摘要
关中盆地地质环境条件复杂,在城市建设及新型城镇化过程中,以往的城市周边工程地质研究程度严重制约了城市的可持续发展,因此开展城市周边工程地质分区与评价研究已成为当前新型城镇化发展工作中的关键环节。以西安灞桥南部地区为例,在已有地貌和岩土体类型划分的基础上,并根据湿陷量计算值将研究区划分为非湿陷区,Ⅰ、Ⅱ、Ⅲ和Ⅳ级湿陷区,在此基础上进行了工程地质分区与评价。综合考虑地形地貌、工程地质、水文地质及存在的主要环境地质问题,采用多因子分级加权指数和法的定量评价方法,开展了研究区建设工程适宜性分区评价。研究成果可为中国范围内相似地质条件下的工程建设规划和设计提供指导和借鉴。
Guanzhong Basin geological environment condition is complicated,during the process of city construction and new urbanization,the city surrounding and the engineering geology seriously restricted the sustainable development of the cities,so it is the key link in new urbanization development work to carry out the study and evaluation of engineering geological zoning around the cities. Taking the southern area of Baqiao district in Xi'an as an example,based on the existing topography and soil type in the study area,and according to the calculated value of the amount of collapsibility,the study area is divided into non-collapsible region,levelⅠ,levelⅡ,level Ⅲ and level Ⅳ grade collapsible zone. On the basis of these,engineering geological zoning and evaluation are carried out.Considering the topography,engineering geology,hydrogeology and the main environmental geological problems,the quantitative evaluation method of multi factor weighted classification index and method is used to carry out the suitability evaluation of the construction projects in the study area. The results can provide guidance and reference for engineering construction planning and design under similar geological conditions in Nationwide.
