在日东高速公路K219+842～K220+060工后缺陷区路段综合处治实践中,利用综合勘察方法明确缺陷原因和范围,提出了对出现裂缝和沉降量较大或地基在压缩主固结阶段的路基,采取竖、斜孔注浆对地基路堤进行加固的方案,质量检测的方法和相应的检测标准,及工后缺陷路段加固处理设计原则和可选方案以及分段对待、标本兼治的综合加固技术。 In the comprehensive treatment of the road sections of the post-construction defect zone of K219 + 842 ~ K220 + 060 on the East-East Expressway, the comprehensive investigation method is used to clarify the cause and scope of the defects. It is proposed that for cracks and subsidence with large amount of settlement or foundation consolidation during compression Of the roadbed to take vertical and inclined hole grouting reinforcement of the foundation of the embankment program, the quality of testing methods and the corresponding testing standards, and post-mortem sections of the reinforcement design principles and options, as well as the treatment of both symptoms and syndromes Reinforcement technology.
