我国丘陵山区地形地貌、水文地质环境复杂,岩性多样,从而造成农村道路路基土体的力学特性各异,因而,对不同自然条件下路基稳定性设计提出了更高的要求。如路基的材料选用、软路基的填充压实、路基沉降垮塌与拓宽垫高、路基边坡防滑稳定、路基的防护与加固、路基排水、路基的施工工艺等处理技术。
The topographic and geomorphological, hydrogeological and environmental complexities and the diversity of lithology in the hilly and mountainous regions in China result in different mechanical properties of subgrade soils in rural roads. Therefore, higher requirements are put forward for the design of subgrade stability under different natural conditions. Such as the selection of subgrade materials, filling and compaction of soft roadbed, collapse and broadening of subgrade settlement and uplifts, non-slip stability of roadbed slope, subgrade protection and reinforcement, subgrade drainage, subgrade construction technology and other processing technologies.
