摘要
贵广铁路地质条件复杂，部分隧道穿越可溶岩地段，且全线采用无砟轨道，对沉降要求非常严格，因此，基底岩溶处理是隧道岩溶整治的关键环节，也是隧道岩溶整治设计的重难点。
Guiyang-Guangzhou railway has complex geolog-ical conditions, section tunnel through karst section, and al use of bal astless track, it has very strict requirements on set lem-ent, therefore, substrate processing is a key link of karst tunnel karst remediation, and the heavy and difficult of tunnel karst treatment design.
