| 高速公路路堤边坡 Highway embankment slope 路基下边坡一般为填土路堤。受力稳定的路堤边坡的破坏，主要表现为边坡坡面及坡脚的冲刷。坡面冲刷主要来自大气降水对边坡的直接冲刷和坡面径流的冲刷，使路基边坡沿坡面流水方向形成冲沟，冲沟不断发展导致路基发生破坏；沿河路堤及修筑在河滩上、滞洪区内的路堤，还要受到洪水的威胁，这种威胁表现为冲毁路堤坡脚导致边坡破坏。 The subgrade slope is usually filled with embankment. The force stability of embankment slope failure, mainly for slope and slope erosion. The surface erosion mainly from atmospheric precipitation on the slope erosion and runoff erosion directly, the subgrade slope formed along the slope direction of the water flow gully, gully development of the roadbed damage; along the river embankment and built in flood and flood detention area within the embankment, but also by the flood threat, this threat is destroyed by the toe of the embankment lead to slope failure. |
