摘要
根据高应变法速度时程曲线在桩底的反射情况和力的时程曲线可判断桩底持力层岩土承载性状,并应用曲线拟合法分析承载力,以此进行桩底持力层岩土状况监控,在遇水易软化的风化岩层地质条件下的桩基承载力检测提供借鉴经验。
The pile＇s supporting course load-carrying behavior can be judged according to reflection case of speed time interval curve at the bottom of pile and force time interval curve in high strain dynamic testing,and it＇s bearing capacity can be analyzed by the method of curve fitting,which can monitor the behavior of supporting course at the bottom of pile when the geological conditions is easy to become soft with water and provide with experience for beating capacity testing of pile under analogous geological conditions in this Province.
