一般路基通常指在良好的地质与水文等条件下,填方高度和挖方深度不大的路基。通常认为一般路基可以结合当地的地形、地质情况,直接选用典型断面图或设计规定,不必进行个别论证和验算。对于超过规范规定的高填、深挖路基,以及地质和水文等条件特殊的路基,为确保路基具有足够的强度与稳定性,需要进行个别设计和验算。 Common subgrade usually refers to the subgrade of the fill height and excavation depth under the conditions of good geology and hydrology. Generally considered that the general subgrade can be combined with the local topography, geological conditions, the direct use of typical sections or design requirements, without having to make a separate argument and checking. For those high-fill and deep-buried roadbeds that exceed the specifications and subgrade with special conditions such as geology and hydrology, individual design and checking are required to ensure that the embankment has sufficient strength and stability.
