路基是公路的重要组成部分之一,是施工单位按照设计图纸的线路位置和技术要求而修筑的带状构造物,主要用于承受来自路面的载荷,路基应有足够的强度、耐久性和稳定性。路基的强度和稳定性受到多种客观因素影响,同时也受到路面车辆载荷的影响,此外录机的设计方案、施工方法和道路养护方法是否正确等人为因素对路基的稳定性与强度也有很大影响。 Subgrade is one of the important parts of highway. It is a strip structure built by construction unit according to the line location and technical requirements of the design drawings. It is mainly used to bear the load from the road surface. The subgrade should have sufficient strength, durability and stability Sex. Subgrade strength and stability are affected by many objective factors, but also by the impact of road vehicle loads, in addition to video recorder design, construction methods and road maintenance methods are correct and other human factors on the stability and strength of the subgrade is also great influences.
