摘要
在高填方路基施工过程中,通过地基处理、沉降观测及选择路面施工时间等方法以避免产生纵向裂缝。而一旦纵向裂缝出现,应及时分析原因,结合边坡稳定分析、注浆和土工格栅等应急处置措施来有效地降低纵向裂缝对路基稳定的影响。
During high fill subgrade construction,longitudinal crack is prevented by foundation treatment,settlement observation and selecting the time of pavement construction.When longitudinal crack appears,the causes shall be analyzed timely combined with slope stability analysis and emergency treatment measures such as grouting and geogrid to effectively reduce the influence on subgrade stability by longitudinal cracks.
