摘要
介绍分析了PHC桩试桩过程中的高应变动测在可打性分析、锤击能量与锤击力监测、桩长与极限承载力关系、初复打对比试验等中的应用。高应变动测为PHC工程桩打桩中的送桩器能量损耗、桩身损坏、停锤标准等分析提供了依据 ,可以为相关工程提供借鉴。
The results of high strain dynamic testing of PHC pile driving are presented herein.The blow count and maximum compression stress varying with the depth are obtained during driving PHC pile.The energy loss of chaser and the damage of pile shaft are analyzed for PHC pile driving by high strain dynamic testing.
