Three-dimensional numerical analysis mechanical behavior of a constructing diaphragm wall panel

The construction sequences of a diaphragm wall panel are simulated by the three-dimensional finite difference method. Ground responses including stress state and deformation of the surrounding ground adjacent to the excavated trench, are studied. Furthermore, the comparison between computed results and field measurements shows that the variation law is quite similar; while the variation of numerical data is a little greater than that of the measurements, especially around the toe of the trench. It can be concluded that this method can simulate the construction process of diaphragm wall well.
