| 摘 要： | 宜万铁路DK345+960-DK347+030段属于覆盖型岩溶环境区,曾发生多次地面塌陷.为保护铁路路基的安全稳定.设计采用钻孔压力注浆处理路基地基.经对注浆处理覆盖型岩溶地面塌陷机理和本段水环境条件的分析,采取了盖板预留地下过水通道、施工严格控制注浆处理范围等措施,既加固了岩溶路基,又保护了水环境,使铁路附近的井泉水质水量未受注浆的影响.

| Abstract: | Due to covered karst region,several surface collapses have occurred in the segment from DK345+960 to DK347+030 of Yichang-Wanzhou Railway.For purpose of keeping safety and stability of railway roadbed,the method of borehole pressure grouting is adopted to deal with its foundation.Through the analysis on collapse mechanism of covered karst surface and water environment conditions after grouting,it is found that the measures adopted,underground path for transferring water reserved by cover plate and grouting ... |
