摘　　要：本研究旨在对南京某地铁长江段拟建项目区的地质条件进行评价。该区域地壳运动相对稳定,适宜项目建设;地层主要由第四系松散层和白垩纪上统浦口组以及震旦系上统灯影组基岩组成;横向地基岩性及压缩性的变化较大,属于不均匀地基,易引起地基的不均匀沉降;白垩系浦口组泥岩、泥质粉砂岩和震旦系灯影组白云岩、白云质砾岩可作为桩基持力层。该研究可为未来在该地区进行的工程项目地质条件评价提供参考。The purpose of this study is to evaluate the geological conditions in the proposed project area of the Yangtze River section of a subway in Nanjing.The crustal movement in the area is relatively stable and suitable for project construction.The strata are mainly composed of Quaternary loose sediments,Upper Cretaceous Pukou Formation and Upper Sinian Dengying Formation bedrock.The transverse foundation have large variations in lithology and compression,which is an uneven foundation and prone to cause uneven settlement of foundations.Mudstone and argillaceous siltstone of Cretaceous Pukou Formation and dolomite and dolomitic conglomerate of Sinian Dengying Formation can be used as pile foundation bearing beds.This study may provide an important reference for the geological condition evaluation of future engineering projects in this area.
