摘　　要：夯实水泥土桩复合地基是近年来发展起来的新的地基加固技术,适用于处理地下水位以上的填土、粉土及粘性土。具有技术先进、经济合理、施工速度快、能较大幅度提高承载力等特点,经过石家庄某原油库区的应用实践证明,夯实水泥土桩法处理油罐地基,其复合地基承载力可达到250kPa,试水后基础沉降量29mm以下。夯实水泥土桩法开辟了处理大型油罐地基的新途径。Composite ground with tamped concrete stake is a new technology developed in recent years for ground reinforcement. It is suitable for the treatment of filling soil, powdered soil or clay, which is above the underground water level. It has the characteristics of advanced technology, reasonable economy and rapid construction speed. Meanwhile the bearing capacity can be greatly enhanced. The application of the technology in a crude storage tank area in Shijiazhuang shows that bearing capacity of composite ground has reached 250 kPa and the ground settlement is less than 29 mm after the water test. So it opens up a new route for ground treatment of large-scale oil storage tank.
