摘要
结合具体工程实例验证了钻孔灌注桩桩端后压浆的有效性,分析了桩周土层性质、桩长、桩径、浆液的类型、压浆量、压浆压力等因素对桩端后压浆桩承载力的影响,得出了后压浆提高承载力的机理。
Combining with the factual engineering examples, the paper proves the effectiveness for the base post-grouting of the bored pile, analyzes the factors, including the property for the soil layer of the pile, the pile length, the pile diameter, the types of slurry and the grouting pressure on the base post-grouting loading capacity, and concludes the mechanism of the post-grouting on improving loading capacity.
