Deformation characteristics analysis of braced excavation on soft clay

The magnitude and location of maximum lateral wall deflection,settlement of adjacent existing buildings,and time effect of deformation of more than ten excavation cases on soft clay in Hangzhou and Shanghai are analyzed in this paper,and the results are compared with that given before.Then an empirical settlement formula is provided based on the settlement mechanism of adjacent existing building and field observation data. Finally,some referable conclusions are obtained.
