南京市地基稳定性区划图

为了城市土地的合理使用，保证建筑物的安全，目前在城市岩土工程问题中对土地的合理利用研究和评价方法不断涌现。本文根据南京市的基岩岩性、地貌特征、覆盖层厚度和第四纪松散沉积物分布情况，划分为五个基本类型，各个分区具有不同的工程地质特征。

A FOUNDATION SUITABILITY MAP OF NANJING CITY,JIANGSU PROVINCE,P.R. OF CHINA

To meet the growing requirements for suitable and safe constructional lands, methods of land-use evaluation are being rapidly developed in engineering geology. The paper deals with setting up a foundation suitability map for Nanjing city. The bedrock geology, topography, the depth to the bedrock and the Quaternary geotechnical soil maps are utilized to achieve this goa1. For simplicity and from practical point of view, the pre-existing maps are modified in simple versions. Each map is separated into areas of different ranges. The zoning map of the engineering geological conditions is prepared by simple superimposing transparent overlays of the four basic data maps. Each zone is rated and five classes of ground conditions fire fabricated.
