摘要
结合某高速铁路岩溶路基段处理的成功实践,详细阐述了该段路基的处理方案和施工方法。压水试验和物探检测结果表明,注浆处理后使强度得到了提高,岩土结构得到了改变,地下水的潜蚀和渗透通道得到了堵塞,溶蚀塌陷从根本上得到消除,为岩溶软土路基的处理技术提供了新的资料。
This paper elaborates the treatment proposal and construction method of a karst subgrade section in one high speed railway in combination with its successful application. The results of packer test and geophysical prospecting test show that the grouting treatment can change the structure of rock and soil and enhance its strength, block infiltration of groundwater and the underground erosion passage, eradicate the formative cause of corrosion and collapse, and present newly technological data of treatment of soft soil subgrade in karst area.
