Zusammenfassung: | The invention discloses a novel layered foundation treatment method for a soft foundation of a closed drainage open channel of a red mud reservoir, which comprises the following steps of: digging red mud (2) to a red mud lower digging line (1) at the position of the closed drainage open channel of the red mud reservoir, airing for two days to evaporate surface moisture, and backfilling and paving an ash water absorption layer (3) at the upper part of the red mud lower digging line (1) to neutralize the moisture; furthermore, layered foundation treatment is carried out by adopting a gravel foundation layer (4), a lower geogrid lower layer (8-1), a lower gravel foundation layer (5), an upper geogrid upper layer (8-2) and an upper gravel foundation layer (6), and finally, a silty clay cushion layer (7) is backfilled to further level the top surface of the foundation so as to ensure the construction quality of the drainage open channel (9), so that the stability and the bearing capacity of the foundation are impr |
