Geogrid-reinforced railroad bed settlement due to cyclic load
Abstract Results of large-scale laboratory model tests conducted to determine the permanent settlement due to cyclic load of the railroad bed for a proposed high-speed train route extending from Seoul to Pusan in South Korea are reported. The possibility of using geogrid layers as reinforcement to reduce settlement of the subbase layer was investigated. Based on the present model test results, it appears that practically all permanent settlement due to cyclic load is completed after application of $ 10^{5} $ cycles of load. The most beneficial effect of reinforcement is derived when one layer of geotextile and one layer of geogrid are placed at the interface of the subgrade soil and subbase course.
