Static and dynamic analysis of Lali bridge basin and caisson foundation

The static and dynamic analysis of Lali bridge basin and caisson foundation is discussed in this paper. The bridge is on Karoon River at elevation 240 m. The river water level is now at 110 and after water is impounded behind Gotvand Dam, the water level will rise to 235 meter. The bridge is cable stay type and will basically rest on two piers, each having two caissons foundations. The caissons have a deck of 16 by 32 meter with 5 meter thickness and are of diameter of 10 meter and depth of 20 meter in rock foundation. The submergence has important consequences on the basin stability and caisson design. The heave and stability of the basin as well as the details of the geotechnical design of the foundation caissons will be discussed.
