针对京沪铁路既有路桥过渡段结构变形不一致的问题,通过原因分析,提出了注浆加固的方法,并阐述了注浆技术加固过渡段的工程措施及注意事项,最后对注浆加固效果进行了现场原位测试、室内土工试验以及动态测试,得出注浆效果能够满足既有线过渡段加固要求的结论,值得在既有线加固过渡段施工中推广应用。
In view of the inconsistent deformation of the transitional section between the existing road and bridge in the Beijing-Shanghai Railway, the method of grouting reinforcement is proposed through the analysis of reasons and the engineering measures and precautions of the grouting reinforcement section are described. Finally, the grouting reinforcement effect In-situ test, indoor geotechnical test and dynamic test were carried out. It was concluded that the grouting effect could meet the requirements of reinforcement of existing transitional lines. It is worth popularizing and applying in the construction of transitional section of existing lines.
