摘　　要：针对港口后张法预应力混凝土大管桩灌浆生产的质量控制,做了压浆料配比、生产及施工工艺条件对比试验。试验结果表明:压浆剂和水的用量对浆体稳定性影响显著,现场原材料试验确定压浆料配比对压力灌浆生产质量控制是非常必要的;正确的生产、施工工艺可有效提高浆体密实性,不仅是压力灌浆生产质量控制的关键过程,还是实现结构安全性、可靠性与耐久性的有利保障。For the control quality of production about pressure grouting on port engineering large diameter post tensioned prestress concrete cylinder pile, the contrast tests of under different conditions, the influence of pressure grouting and production and construction technology are carried out. The results show that the influence of the dosage of the grouting agent and the water is significantly on the stability of slurry, and it＇s very necessary to determine the pressure ratio to the quality control of pressure grouting production by the raw material test; the correct production construction technology can effectively improve the density of slurry, that is the key process to the quality control of pressure grouting and the guarantee to realize structure security, reliability and durability.
