High-intensity group of geological formations of granite seokjeong lands distributed in eastern coastal areas of Guangdong province widely. Geological problems have become prominent increasingly with the region＇ s rapid expansion of urban construction, which caused certain obstacles to the construction. This article focuses on foundation application and processing method of PHC composite foundation in granite seokjeong lands. Combined with the geological stratum of Guangdong province coastal areas and the characteristics of the construction, through the engineering example, to analysis the causes and characteristics of prestressed pile composite foundation in the area. And make the appropriate treatment plan for the construction of similar areas as reference.
