摘　　要：圣多美和普林西比首都国际机场改扩建项目场地地貌复杂多变,软土、有机土、多旋回火成岩等岩土类型多样且分布复杂。为获得相对准确的岩土工程设计参数,保障后期工程的顺利实施,在细致分析场地区域地质特征及地形地貌的基础上,综合使用踏勘、钻探编录、室内试验、原位测试等方法,结合国内外岩土工程勘察经验,对该复杂场地的岩土工程特性进行分析研究,提出了分区地基处理的原则和措施,分析和预测了后期施工和运行可能引起的工程地质问题,并提出防治措施,以满足岩土分析评价和设计要求。In the geotechnical engineering investigation of the reconstruction and expansion of the Capital International Airport in Sao Tome and Principe,the topography of the site is complex and changeable,where soft soil,organic soil and multi-cyclic igneous rock are widely distributed in land and sea sites.To obtain relatively accurate geotechnical engineering design parameters and ensure the smooth implementation of the later stage of the project,based on detailed analysis of the regional geological characteristics and landforms of the site,a variety of methods such as field survey,drilling catalog,laboratory test and in-situ testing are adopted.In this paper,by years of geotechnical investigation experience at home and abroad,the authors analyze and study the geotechnical engineering characteristics of the complex site,propose the principles and measures of subdivision foundation treatment,analyze and predict the geological problems that may be caused by the later construction and operation,and put forward the prevention measures,which meet the requirements of geotechnical analysis,evaluation and design.
