摘要
粤东沿海地区普遍发育着花岗岩地貌,因长期的地质风化作用出现孤石群地层,随着该区域城市建设的大力扩展,基础设计和施工困扰日益突出,给工程建设造成一定障碍。本文结合粤东沿海区域地层结构及工程建设的特点,通过工程实例,分析预应力管桩复合地基在该区域应用的特点,并给出相应的处理方法,为类似地区工程建设的基础处理提供参考。
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.
