| Abstract: | The landslide process of a composite soil nailed wall in soft clay excavation is described . The causes of the landslide are analyzed and the corresponding treatment measures are proposed. The failare mechanism of soil nailed wall in soft clay or residual soil excavation is discussed;and the soft clay excavations can be classified into two strata soft clay and three strata soft clay excavations. The three strata soft clay excavation with composite soil nailed wall is superior to the twostrata soft clay excavation with composite soil nailed wall in deformation-controlling and stability. |
