铁路路堤是取自天然土石作为建筑材料而修成的土石结构物。它承受轨道和列车荷载,还常年暴露在自然界,受风吹雨打的侵袭,使它的工作条件处于十分恶劣的状态。为此,要做到路堤坚固而稳定,需要考虑的技术问题是较复杂的。但不论设计或施工,首先得知填筑 Railway embankment is taken from the natural rock as a building material and built earth and rock structure. It withstands rail and train loads, but also perennial exposure to nature, affected by wind and rain attacks, making its working conditions in a very harsh condition. Therefore, to make the embankment firm and stable, the technical problems to be considered are more complex. However, no matter the design or construction, we must first know the construction
