摘要
根据对位于断裂破碎带上的桩基进行桩底压力注浆和基桩高应变动力检测,介绍了桩底压力注浆的工艺流程、技术参数及注浆效果,并对压力注浆提高人工挖孔桩极限承载力的机理进行了分析。
Based on the in-situ pressure-grouting experiments and the high strain dynamic tests of hand-formed pile built on the fracture zone, the process, parameters and effect of pressure grouting are introduced in this paper. The mechanism of increasing the ultimate bearing capacity of the piles by grouting is analyzed.
