| Abstract: | Abstract: Gravity retaining wall is a kind of retaining structure that is often used in Shanghai soft deposit. There are some lateral deformation calculation methods of gravity retaining wall. However, most of them are too complicated to be used and only few of them are suitable for engineers. The lateral displacement function of the gravity retaining wall was normalized through several excavations in Shanghai. The simplified formula of lateral deformation of gravity retaining wall was deduced through principle of minimum potential energy. Meanwhile, factors that affect deformation of gravity retaining wall were also analyzed. The simplified formula was adopted to calculate the lateral displacements of gravity retaining walls of ten excavations. The average relative error between the calculated results and the measured results is 13.5%. This has proved that the method is suitable for calculating lateral displacement of gravity retaining wall. |
| Keywords: | gravity retaining wall principle of minimum potential energy lateral deformation excavation calculation method |
