挤密砂桩复合地基承载力的计算研究

Calculation of bearing capacity of composite foundation of compacted sand piles

以小漠国际物流港(一期)陆域形成工程为背景,对挤密砂桩复合地基承载力的计算进行研究,其中砂桩单桩承载力计算采用Brauns法和被动土压力法,经过对比计算,采用被动土压力法对计算复合地基承载力更准确,并结合现场试验,确定了被动土压力公式的修正值0.73。

In this paper,the bearing capacity of the composite foundation of the compacted sand pile is studied by using the land formation project of the small international logistics port（ Phase I） as the engineering background.The bearing capacity of the single sand pile is calculated by using the Brauns method and the passive earth pressure method,through comparative calculation,the passive earth pressure method is more accurate for the calculation,in combination with the field test,the correction value of the passive earth pressure formula is determined as 0. 73.
