砾卵石层冲孔灌注桩桩端注浆后的承载性状研究
Behavior of Boring Cast-in-Situ Piles Based on Gravel Layers After Grouting at Piles Tips
【摘要】 依据某工程6根支于砾卵石层且经桩端后注浆的冲孔灌注桩单桩竖向抗压静载试验及其中3根试验桩桩身受力测试结果,对其Q-s曲线的特性、桩身轴力传递机理、桩侧阻力和桩端阻力发挥性状进行分析,揭示了注浆后冲孔灌注桩的承载性状及桩侧、桩端阻力的发挥性状,对冲孔灌注桩的设计和深入研究提供参考。
【Abstract】 According to the results of six in-situ pile load tests of boring cast-in-situ piles after grouting at the piles tips and the tress distributions of three of those piles,theirQ-scurves,tress transferring of piles,pile side frictions and pile tip resistances affected by grouting,were analyzed in details.
