摘要
依托野外调查和资料分析的基础上,将研究区工程地质分区划分为5个大区、10个亚区,分别为长江冲积平原工程地质区(Ⅰ1、Ⅰ2)、局部小流域冲积平原(青弋江)工程地质区(Ⅱ1)、局部小流域冲积平原(漳河、横山河)工程地质区(Ⅲ1、Ⅲ2)、岗地工程地质区(Ⅳ1)、和山地丘陵工程地质区(Ⅴ1、Ⅴ2、Ⅴ3、Ⅴ4)。同时采用多因子分级加权指数法,对研究区进行工程建设适宜性评价,结果表明:研究区内的长江两侧均为较不适宜工程建设的区域,面积约79.19 km2;较适宜工程建设的区域主要位于长江的北岸及小部分区域南岸,面积299.46 km2;适宜工程建设的区域主要位于长江南岸,面积约345.85 km2。
On the basis of field investigation and data analysis,the engineering geological division of the study area is divided into 5 large areas and 10 sub regions,which are respectively the Yangtze River alluvial plain engineering geological area( Ⅰ1、Ⅰ2),the local small watershed alluvial plain( Qingyi River) engineering geological area( Ⅱ1),and the local small watershed alluvial plain( Zhanghe River,Hengshan River) engineering geological area( Ⅲ1、Ⅲ2),hill engineering geological area( Ⅳ1),and mountainous and hilly engineering geological area( Ⅴ1、Ⅴ2、Ⅴ3、Ⅴ4). At the same time,the multi factor grading weighted index method is used to evaluate the suitability of engineering construction in the study area. The results show that both sides of the Yangtze River in the study area are not suitable for engineering construction,covering an area of 79. 19 km2;the more suitable areas for engineering construction are mainly located in the North Bank of the Yangtze River and the South Bank of a small part of the area,with an area of 299. 46 km2;the suitable area for engineering construction is mainly located in the South Bank of the Yangtze River It covers an area of 345. 85 km2.
