【摘要】：以西安地鐵某號線穿越飽和軟黃土地段為研究對象,針對施工中采用的全斷面注漿加固地層措施,分析其合理的注漿半徑。利用FLAC3D數(shù)值模擬軟件,重點分析地鐵隧道穿越飽和軟黃土地層時不同注漿半徑下的圍巖豎向變形,并結(jié)合相關(guān)工程經(jīng)驗,確定合理的注漿半徑。分析結(jié)果表明,針對本工程實際地質(zhì)水文條件,合理的注漿半徑為2~3 m。其可為類似地質(zhì)條件下的工程提供借鑒。
[Abstract]:Taking a certain line of Xi'an Metro through the saturated soft loess section as the research object, the reasonable grouting radius is analyzed in view of the measures adopted in the construction of the whole section grouting to reinforce the stratum. By using FLAC3D numerical simulation software, the vertical deformation of surrounding rock under different grouting radii of subway tunnel passing through saturated soft loess layer is analyzed, and the reasonable grouting radius is determined by combining with relevant engineering experience. The results show that the reasonable grouting radius is 2 ~ 3 m in view of the actual geological and hydrological conditions of the project. It can be used for reference for similar geological engineering.
