Research on Red Sandstone Area Expressway Subgrade Drainage System Design
Aimed at the feature of expressway subgrade drainage facilities in typical red sandstone areas in Jiangxi province and based on the importance of the structure, damage conditions, service requirements and the current specification requirements related to various types of ditches, the designed repetition period of rainfall and proposed safety depth values for drainage facilities were put forward by considering reasonably the key design parameters to regional drainage facilities. The relationship between prerequisite of discharging sediment in ditches or conduits and minimum longitudinal gradient was discussed. Combined with the characteristics of red sandstone subgrade drainage with high requirements, the design elements of red sandstone area expressway subgrade drainage system were obtained, which can provide beneficial references for the subgrade drainage design in red sandstone areas.
