摘要
上海地区第四纪时期古河道发育,其中晚更新世以来的古河道对工程建设影响最大。根据大量钻孔及测试资料,研究了晚更新世末期古河道、全新世晚期吴淞江古河道和近代古河道的成因、分布规律及沉积物特征。在此基础上,结合上海市工程建设特点,系统分析了古河道对工程建设,尤其是地下空间开发的影响,成果可为工程勘察、设计、施工提供基础地质依据。
In Shanghai land area,many ancient river beds developed in the Quaternary period.The ancient river channel beds since late Pleistocene have substantial effects on construction.Based on large amount of drillhole and test datum,this paper presents the genesis,distribution,and sediment characters of the ancient river channels in late Pleistocene,Holocene,and present years.This paper further analyzes the effects of ancient river channels on construction,especially underground projects.The results of this paper can be used as the basis of investigation,design,and construction of new projects.
