Abstract
Diaphragm walls and anchor rods are generally provided to support open berth structures in marine soils. The diaphragm walls are subjected to loads due to the soil layer on one side of the structure. Anchor rods may be provided in order to strengthen the structure and to resist the lateral loads and reduce the deflection to a large extent. In this paper the deep draft berth of new mangalore port provided with diaphragm wall and anchor rods is analysed using finite element software PLAXIS 3D. The displacement, shear force and bending moment are found out for diaphragm wall for the cases of with and without anchor. The comparison is made on depth V/s bending moment, depth V/s shear force and depth V/s deflection of the diaphragm wall. In the case of diaphragm wall without anchor rod, the maximum bending moment, shear force and deflection were found to be 23553 kN-m, 1743kN and -0.0693m respectively. The percentage reduction in bending moment, shear force and deflection were found to be 63.06%, 18.53% and 93.56% for the case of diaphragm wall with anchor at +2.5 m. In this research paper, analyses are performed by varying the location of anchors to find the optimum.
