摘　　要：CFG桩又称为水泥粉煤灰碎石桩,它以水泥(Cement)、粉煤灰(Fly ash)和碎石(Graval)等材料按比例拌和灌筑而成.粉煤灰是工业废弃物,作为主材料形成复合地基,不仅符合我国节能减排绿色发展的政策要求,而且具有良好的性能,处理软土地基的加固效果明显,因此工程中得到了广泛应用.介绍某装置中的6座2万m^3重油储罐,采用CFG桩复合地基做建造基础,并且这些储罐使用多年后其被加固过的地基仍然结实牢固.CFG piles, also known as cement fly-ash gravel piles, are made of cement, fly ash and gravel in proportion. Using fly ash, an industrial waste, as the main material to reinforce soft soil foundation not only meets the policy requirements of energy conservation and emission reduction in China, but also has good performance. It has been widely used for treating soft soil base. The project in this paper involves 6 heavy oil storage tanks with a capacity of 20,000 m^3 each. CFG piles are used to reinforce the foundation soil, and the project has been operated for many years.
