Parametric Studies of Ground Deformation Induced by Pneumatic Caisson Construction in Soft Soils
This paper presents a thorough finite element (FE) parametric study of ground deformation caused by the new pneumatic caisson (NPC) construction. In this study, the effects of several parameters which may affect the ground deformation were investigated in terms of two aspects: surface settlements, and soil upheavals beneath the caisson. These parameters are (1) skin friction, (2) compressed air pressures, (3) embedment depth, and (4) distance from the caisson of the protection wall. Based on the proposed FE simulation techniques, the effects of these parameters were quantified and discussed, and the factors that help to reduce ground deformations were identified. Results showed that the compressed air pressures played a very important role in preventing upheavals of soils at the caisson base. Finally, some suggestions and recommendations for NPC construction were reached.
