摘要
桩底注浆技术是近年发展起来的新技术,以苏丹西纳大桥为背景,阐述桩底注浆的机理,介绍西纳大桥桩底注浆的过程,结合中美两国规范,计算西纳大桥注浆后的桩基承载力,最后通过桩基承载力试验验证了桩底注浆的有效性,希望为同类桥梁的设计与施工提供参考。
The technique of pile grouting is developed in recent years,taking Sudan Sinnar bridge as the background,elaborating the mechanism of pile grouting,introducing the process of pile grouting of Sinnar bridge,combining the two countries＇ specifications of China and America,calculating the bearing capacity of pile foundation after grouting of Sinnar bridge,finally,verified the effectiveness of the pile grouting by the bearing capacity tests,Hoping to provide the reference for similar bridges＇ design and construction.
