摘要
碎石桩是一种散体材料桩,广泛应用于油罐、道路、水池和建筑等工程中处理砂土、粉土、粉质粘土、素填土和杂填土等地基,是一种有效而经济的方法。振动沉管碎石桩除具有碎石桩的一切优点外,由于采用振动沉管成桩工艺,使得挤密效果更好。对现有的5种确定碎石桩承载力方法:从基本假定、计算模型、计算公式等方面进行了探讨,并通过某大型油罐地基处理工程采用振动沉管碎石桩的工程实例,将5种计算方法的计算结果与规范法进行了对比。
Gravel pile is a kind of granular material pile.It is an effective and economic treating method widely used in the engineering of oil tanks,roads,water pools and buildings to treat sand, silt, silty clay, soil and miscellaneous fill foundations.In addition to all the advantages of gravel pile,vibration sinking gravel pile has better compaction effect because vibration sinking pile forming technology is used.In this paper,five existing methods for determining the bearing capacity of gravel pile are discussed from the aspects of basic assumptions,calculation model and calculation formula,an example of large oil tank foundation treatment using vibration sinking gravel pile is given,and the calculating results are compared with the specification method.
