摘　　要：特殊类岩土是工程建设的重要影响因素。以江苏丹徒经济开发区为例,基于历史勘察资料和工程地质补充调查成果,研究了镇江长江沿岸特殊类岩土发育的工程地质背景和工程地质特征,并分析了其对工程建设的影响。研究结果表明:镇江长江沿岸发育有软土、膨胀土、液化砂土三种特殊类岩土,分布在长江漫滩平原、岗地不同工程地质区,工程地质性质较差,对工程建设影响程度较大。Special types of rock and soil are significant influencing factors in engineering construction.Taking the Dantu economic development zone in Jiangsu Province as an example,based on historical investigation data and supplementary engineering geological investigation results,this paper studies the engineering geological background and characteristics of the development of special types of rock and soil along the Yangtze River in Zhenjiang,and analyzes their impact on engineering construction.The research results show that there are three types of special rock and soil,namely soft soil,expansive soil and liquefiable sand,distributed in different engineering geological zones of the Yangtze River floodplain and upland.Their engineering geological properties are poor and have a significant impact on engineering construction.
