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.
