摘要
临海高等级公路穿越江苏省连云港、盐城和南通三市,紧邻海岸线,是目前江苏最靠近大海的在建高等级公路。在收集临海高等级公路勘察资料的基础上,查明沿线软土分布特征以及成因,从区域沉积历史和矿物成分来源等几方面,探讨临海高等级公路穿越区域软土的特性。结果表明,临海高等级公路沿线跨越了4个地质分区,软粘土成因与海退、废黄河改道以及长江携沙入海密切相关。
The high-class coastal expressway goes through three cities, including Lianyungang, Yancheng and Nantong, in Jiangsu Province. Close to the coastline, it is the high-class expressway under construction nearest to the sea in Jiangsu. On the basis of the prospecting data collected, the distribution characteristics and the genesis of soft clay along the expressway are found out; and from the aspect of regional deposition history and minerals composition, the features of this expressway crossing the soft soil in the region are discussed. The results show that the high-class coastal expressway spans four geological subdivisions and the genesis of soft clay has close correlation to sea regression, diversion of ancient Yellow River and sediment carried into the sea by Yangtze River.
