摘　　要：随着公路桥梁建设的快速发展,钻孔灌注桩作为桩基础的重要形式之一,其施工技术研究显得尤为重要。为了保障道路桥梁基础的稳定性,提升路桥结构的荷载承载能力,并增强基础设施的整体安全性,研究了公路桥梁钻孔灌注桩施工技术。选择合适的钻孔灌注桩型,根据施工情况计算出桩基承载力,运用钻孔灌注桩后压浆技术来增加桩基的阻力和桩基的极限承载力,进而增强道路桥梁基础的稳定性。由此验证了运用钻孔灌注桩压浆技术的承载力更高、稳定性更佳。With the rapid development of highway bridge construction,bored pile as one of the important forms of pile foundation,its construction technology is particularly important.In order to ensure the stability of the road and bridge foundation,improve the load bearing capacity of the road and bridge structure,and enhance the overall safety of the infrastructure,the construction technology of the bored pile of the road and bridge is studied.Choosing the suitable type of bored pile,calculating the bearing capacity of pile foundation according to the construction condition,using the post-grouting technology of bored pile to increase the resistance of pile foundation and the ultimate bearing capacity of pile foundation,then the stability of road and bridge foundation can be enhanced.It is proved that the bearing capacity and stability of bored pile are better by using the grouting technique.
