摘要
为了解决高速公路采空区路基稳定性问题,结合某高速公路具体情况,通过分析其地质情况及不同年代的采空区特点,采用注浆处治。通过优化注浆半径、注浆重量等参数,达到注浆参数的最佳选择。注浆效果的检测结果表明,采空区注浆处治效果良好。
In order to solve the stability problem of goaf under highway roadbed, In this paper, combined with the specific situation of a highway, through the analysis of the geological conditions and different time in goal by grouting characteristics, treatment~ By optimizing the radius, grouting Grouting grouting parameters such as weight, achieve the optimum parameter selection. The results show that the grouting effect detection, goaf grouting treatment effect is good.
