| Abstract: | In recent years, due to the momentous development of transportation, the existing highways cannot meet the demand of the speedy increase of traffic flow. As a result, many existing highways need to be widened. Based on the real case of applying the technology of soft subgrade treatment to Xiaotang Flyovers in Guangzhou ring-road, the paper introduces the design and application of pre-stressed concrete pipe piles in the widening and reformation of highways. |
