摘要： 近年来，随着我国城市化进程的不断加快，城市人口呈现大规模增长趋势，由此带来的城市交通压力不容小觑。为了缓解这种压力，以地铁为代表的城市轨道交通工程逐渐兴起，而由于地铁设计要求的特殊性和地铁建设场地地质条件的多样性使得地铁工程岩土勘察具有较为鲜明的“个性”。现结合宁天城际轨道交通一期工程雄州站～凤凰山公园站地铁隧道区间的特定地质条件，从场地的稳定性及工程的适宜性、岩土层工程地质评价、地基均匀性评价、特殊岩土以及不良地质等方面出发对南京地铁工程勘察研究的主要内容进行了介绍，并提出了地铁工程勘察中需要注意的问题。

Abstract: With the urbanization development in recent years, the urban transportation is facing the challenge from the urban population increase. The urban rail transportation, as it is represented by the Metro and the light rail system, is usually a good solution to the public transportation in large cities. Due to the special engineering requirements of the Metro system and the geological variation along the subway lines, unique characteristics are existed in the geotechnical investigations for these projects. This paper presents the case study of Metro System between Stations of Xiongzhou and Phoenix Mountain Park of Pahse I of NingTian Intercity Light Rail Project. The geological stability, site evaluation, uniformity of subsurface soils and rock mass, special geomaterial as well as adverse geological condition aspects of the project are introduced. Design recommendations for the Metro System are also presented in the paper.
