结合工程概况,介绍了既有线路基床的加固方案及施工程序,并对采用树根桩加固的基床的加固效果进行了检测,检测结果表明,采用树根桩加固方案加固路基基床对提高地基承载力起到了明显效果,确保了既有线铁路的行车安全。 Combined with the general situation of the project, the reinforcement plan and construction procedure of the existing linebed are introduced, and the reinforcement effect of the foundation bed reinforced by the root stump is tested. The test results show that the reinforcement of the subgrade bed by the root stump reinforcement scheme is effective The bearing capacity of the foundation has played a significant effect, ensuring the traffic safety of the existing railway line.
