A submerged tunnel, attached to the bottom by steel cables is analyzed using semi-analytical finite element methods. The tunnel with an elliptic crosssection with three circular tunnels inside is considered for which two computer programs are developed. The former one beini a plane stress analysis program is used for the analysis of the structure under the effect of the hydrostatic forces and own weight while the second one performs analysis for the lateral current forces. The cross-sectiori is divided into linear .triangular elements then the strains together with the stresses are evaluated for each element separately. Furthermore, the principal stresses and their respective directions are obtained for design purposes.
