The pile-end post-grouting technology can increase the bearing capacity of piles and improve the bearing performance of piles.
桩端后压浆可以提高桩的承载力,改善桩的承载性状。
The paper describes the conditions of realizing reasonable pile end grouting; pile end grouting can improve mechanics of single pile bearing capacity and impact analysis of grouting reinforcement.
并阐述了实现合理的桩端注浆条件,桩端注浆提高单桩承载力的机理以及注浆加固效果分析。
The greatly reduced capacity of a single pile resulting from the negative friction leaves the end-bearing pile unsuitable in the backfilling soil.
实例分析表明,由于桩侧负摩阻力的影响,单桩承载力大为降低。产生负摩阻力的土层,不宜采用端承型桩基。
