Based on the analysis of the topography and geology of the loess hilly and gully area in Loess Plateau and the causes of drainage and drainage hazards in the subgrade in the loess plateau, this paper systematically analyzes and studies the technology of subgrade protection and drainage in the area, Conservation technical specifications, put forward loess sub-gully area subgrade drainage technology and disease prevention and control measures from a systematic point of view to build a comprehensive subgrade drainage system should be noted Matters. With a view to further improve the highway construction technology in the area, effectively control and reduce water damage, to ensure the stability of roadbed.
