预制桩锤击打入法在地基处理中的应用

Application of precast piles driving method by hammer in ground treatment

结合工程实例叙述了预制桩锤击打入法在地基处理工程中取得了良好的效果 ,从锤击法的沉桩机理、施工工艺等方面进行了论述 ,解决了桩体的偏移和倾斜、桩体破损、沉桩困难等问题 ,分析了地基土质变化 ,并采取了相应的措施 ,得出了预制钢筋砼桩是一种很有效的地基处理方法。

combining with engineering examples, the paper recounts fine effects of application of precast piles driving method by hammer in ground treatment, discusses principle of sinkpile by hammer, engineering examples, construction technology and so on, solves some problems of offset, tilt and breakage of pile body, making difficultly piles sink, analyses the change of ground soil property, taking appropriate measures, obtains that precast reniforced concrete piles are a kind of very effective method of treating ground.
