一路基工程是把现代有关路基的科学与技术知识应用于路基设计、施工与养护,以保证路基的稳定性和可靠性。修建铁路中路基工程量最大,投资一般也最多。路基强度和稳定不仅关系线路修建和维修费用,更重要的是直接影响铁路运输效率及安全。因此路基工作在铁路中具有极其重要的地位。铁路路基工程是轨道的基础,它长期遭受列车冲击,同时受到自然侵蚀和人为活动影
A roadbed project is the application of modern knowledge of subgrade science and technology in roadbed design, construction and maintenance, in order to ensure the stability and reliability of subgrade. Construction of the railway project in the largest amount of roadbed, investment is generally the most. Subgrade strength and stability not only related to the cost of line construction and maintenance, more importantly, the direct impact on railway transport efficiency and safety. Therefore, the subgrade work in the railway has an extremely important position. Railway embankment engineering is the basis of the track, it has long been hit by trains, both by natural erosion and human activities
