Stability analysis of cellular retaining structure by PLAXIS finite element code

الملخص EN

In this study, analysis of retaining structure by using the software PLAXIS is adopted and the deformation that occurs in the body of the retaining structure after applied the failure load detected ; the failure loads are obtained from the series of laboratory tests.

Then, the cofferdam is modeled by using finite element code PLAXIS.

The laboratory tests have been carried out two diaphragm cells of different width to depth ratios, and used three different soil materials (subbase, sand passing No.4, river sand, and clay).

The analysis includes studying the effect of height, width, and embedment depth.

The input data of soils that are used in this software are getting from these laboratory tests.

The comparison is done between the deformation that is obtained from the actual experimental and the software PLAXIS.

It can be seen that the displacement for the retaining structure place on ground surface in the laboratory test equal to 0.00322m and the displacement that obtain from PLAXIS equal to 0.00372m, and the displacement for retaining structure with embedment depth in laboratory test equal to 0.00321m and the displacement from software PLAXIS equal to 0.00263m.

Thus, the results from these two studies have been found closed to each other.
