钻孔灌注桩桩端后注浆单桩极限承载力研究
Study on Ultimate Load Bearing Capacity of Post-Grouted Bored Piles
【摘要】 桩端后注浆技术是增加桩端面积及提高桩端面上的单位面积阻力的方法之一。本文分析了桩端后压浆技术适应的地质条件和有关技术参数,提出单桩极限承载力的计算方法,作为初步设计依据,结合宁波地区的几项工程实例,进行了分析验证。
【Abstract】 The post-grouting technology is one of the methods to increase the base areas and base resistance pressure.The suitability of the geological conditions and technical parameters for the technology is discussed,and a formula,which was examined and verified by the cases in Ningbo area,for calculation of the bearing capacity for post-grouted piles was suggested as a initiative base of design.
