| Abstract: | in this paper, the stress and deformation of the 2nd-stage cofferdam with double high diaphragm walls in the Three Gorge Project are analysed using GEOTL, a three-dimensional finite element program. The stress-strain behavior is expressed by the hyperbolic model. The stresses and displacements in the construction process are presented, and the vulnerable parts of the cofferdam are pointed out. |
