Abstract:The three-dimensional finite element models for two construction procedures were established separately for making comparisons on deformation and internal force characteristics between different construction procedures;then deformation and internal force of steel sheet pile on the two construction procedures were analyzed and compared with the monitoring values. It has been found that deformation and bending moment were greatly reduced on improved construction procedure that could play a strong role in coordination,improving safety and expanding application range of steel sheet pile cofferdam. At the same time,it was also shown that characteristics of deformation and internal force on improved construction procedure were different with conventional construction procedure owing to its outstanding three-dimensional feature;and some dangerous zone ignored regularly should be noticed extremely in design and construction.
