摘　　要：结合具体工程实例,通过对普通桩和桩端后压浆桩的对比试验,分析了桩端后压浆对桩承载性能的影响,分析结果表明,桩端后压浆技术可以很好地提高单桩承载力和刚度,桩端后压浆对提高单桩承载力有很好的时间效应和经济效应。Combined with specific engineering example, through comparing test of common pile and pile end post grouting pile, the pile end post grouting pile influence on pile bearing behavior was analyzed. The analysis result indicated that pile end post grouting technology can enhance single pile bearing capacity and rigidity commendably. The pile end post grouting pile had better time effect and economic effect to enhance bearing capacity if single pile.
