Abstract : This graduation design task is to conduct a three highway construction design (K5+600~K7+000). According to China's "natural divisions highway standards," Hunan is hilly and wet Jiangnan (FROM) mainland-humid monsoon climate, mild spring and autumn, summer heat Standard Specification, four distinct seasons, light enough and bountiful rainfall average rainfall 1200~1500mm spring, summer, heavy rainstorms, 4-8 months, the rainfall-more than 60%, in August after rainfall, The annual average temperature in January was 16.5 degrees minimum temperature of 4.3 degrees, the highest temperature in July was 29. On the full range of Mountainous Area 3 highway construction, design speed 30km/ h, the rate of the overall road-section. Road layout of the sites : roadbed width of 7.5m, two two-way lanes, the Land shoulder of 2 × 0.50m. lane 2 × 3.25m. Design flood frequency of 1:250. Abundant along the gravel, sand, and stone mainly limestone, reliable, and transport facili
