阐述了后压浆灌注桩技术、施工工艺及措施，对模型试验桩的静载试验表明，应用该技术可大大提高灌注桩的承载力并使其变形特性得到明显改善．该技术可供其他工程参考． The technology, construction technology and measures of the post-grouting pile were described. The static load test of the model pile showed that the application of the technology can greatly increase the bearing capacity of the pile and significantly improve its deformation characteristics. This technology can be used for other projects.
