桩底压浆技术在洺河渡槽桩基试验与分析

摘要

洺河渡槽通过3根试验桩的桩底压浆前后静载对比试验，测定桩底压浆对桩周侧摩阻力和端承力的增强效果，为桩底压浆提供设计计算参数和施工工艺参数。%Through the static load comparative tests before and after pile-bottom grouting of three test piles in Ming River aqueduct, determining the effect of the pile bottom grouting on pile side friction resistance and end bearing capacity, pro-viding the design calculation parameters and construction process parameters for the pile bottom grouting.
