淮河大堤蚌埠段位于淮河中游,历年汛期最大流量为11600米~3/秒,最高洪水位为22.18米,高于淮河一级阶地,两岸防洪大堤高8—10米。本区大部份为第四系所覆盖。南岸的阶地及山麓丘陵地带,第四系厚10—40米。北岸的第四系厚度,东部一般小于200米,西部为300—500米,最厚达800米。据勘探资料,淮河两岸广泛分布着粉土、粘土、亚粘土以及粉、细砂层。淮河大堤蚌埠段的堤基土层长期处于地下水位以下,在地震作用下,有液化的可
The Huaihe embankment Bengbu section is located in the middle reaches of the Huaihe River. Its maximum flow in the flood season is 11,600m 3 / s and the highest flood level is 22.18m, which is higher than the first terrace of the Huaihe River. The cross-strait flood control embankment is 8-10m high. Most of the area is covered by the Quaternary. South of the terraces and foothills, Quaternary thick 10-40 meters. Quaternary thickness of the north shore, the eastern less than 200 meters in general, the western 300-500 meters, the maximum thickness of 800 meters. According to the exploration data, silt, clay, sub-clay, and fine sand layers are widely distributed across the Huaihe River. The embankment of Bengbu section of the Huaihe River embankment has long been below the groundwater table. Under the earthquake, liquefied
