特殊岩土地层注浆加固技术研究

Research on grouting reinforcement technology for special rock soil strata

在注浆加固技术中,注浆加固配比、注浆压力、扩散半径三者数值的设定比对于工程质量起着举足轻重的作用,采用试验对比法,以某特大桥桩基础施工为例,研究海相沉积松散地层注浆加固配比、注浆压力、扩散半径的最佳方案及效果,以进一步优化注浆加固技术,提高工程建设质量。

In grouting reinforcement technology,the determination of grouting reinforcement ratio,grouting pressure,diffusion radius three numbers played important role in engineering quality,used experimental comparison method,taking a special bridge pile construction as an example,this paper researched the optimal scheme and effect of grouting reinforcement ratio,grouting pressure,diffusing radius of loose strata in marine sediments,in order to further optimize grouting reinforcement technology and improve the engineering construction quality.
