[0002] A buttress retaining wall is a type of retaining structure suitable for embankment areas. It can be used for building embankment retaining walls, highway subgrade support, and riverbank protection projects. A buttress retaining wall is a whole composed of a base plate, vertical plates, buttress plates, and backfill soil.
