摘要
利用多道瞬态面波法对合福高铁安徽段某岩溶路基30%和100%的钻孔注浆质量进行检测。通过注浆探测效果图与现场实际情况对比验证分析,100%的注浆效果图中低速区较30%的注浆效果图明显减少,且异常区被完全充填,说明后期水泥注浆对裂缝填充效果显著,表明该方法在岩溶路基注浆质量检测应用中有显著的效果,且经济快速有效,在岩溶路基工程检测中具有良好的应用前景。
The Multi-channel transient surface wave was used to estimate the karst subgrade grouting quality of Hefu high-speed railway in Anhui which were completed 30% and 100%. Through a comparative analysis of grouting effect detection figure and actual situation on the spot, the low-speed area in surface wave exploration intersection image of grouting completed 100% less than the 30% obviously,and the abnormal area has been filled in completely, this suggests the cement grouting of late in fissure filling effect is remarkable. It indicates that the effect of the method applied in grouting subgrade in Karst geological detection is obvious,and economy, quickly, efficiently, so,it has a good application prospect in the karat roadbed engineering detection.
