Abstract:

With the increase of traffic and the over-load vehicles, the bearing and deforming behavior of retaining structure is increasingly influenced by traffic loads. According to the prestressed anchor sheet-pile wall, using FLAC3D, the spatial analysis model is established. Combining with the field dynamic strain test, the mechanism of bearing and deforming behavior of retaining structure is studied. The results show that the depth of the traffic loads affected is about 2 meters in both subgrade and retaining wall. Under normal circumstances(fully loaded heavy vehicles, driving on a carriageway), the dynamic earth pressure of prestressed anchor sheet-pile wall is approximately 10% of earth pressure at rest.

Key words: prestressed anchor sheet-pile wall, dynamic response, numerical simulation
