Abstract: The rapid urbanization development in China, the construction of high-raised buildings has the function of alleviating the demanding of urban land resources. In recent years, high-raised buildings have become a major structure type in cities. The area of construction for the high-raised buildings is relatively large, and the size of vertical loads is directly proportional to the floor heights. To ensure the smooth construction of the supper structure, restrictive requirements need to be applied for the quality of foundation construction and for the stability of the building foundations. First, geological engineering and geotechnical properties of subsurface materials should be investigated so that a thorough understanding of the geotechnical information can be obtained before the design and construction. Therefore, geological engineering investigation is particularly important in the early stage of a project. This article presents a construction project in Yunfu City as a case history. geological and geotechnical properties of the subsurface soils and bedrock are obtained through drilling and geotechnical laboratory tests. Combining with the sitespecific conditions, the application of geological engineering investigation in construction engineering is analyzed. This case study provides a reference value for similar projects in the region.
