| Abstract: |
| 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 andin-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. |
