This paper presents the results of a numerical investigation on the behavior of deep excavation wall system supported by steel pipe struts. A series of three-dimensional finite element analyses were carried out on a braced excavation case which adopted steel pipe struts. The results indicated that the mechanical behavior of the steel pipe supported braced excavation is comparable to that of a conventional H-pile supported excavation, although the steel pipe supported system allows a larger longitudinal spacing than the conventional H-pile strut system. Also shown is that the sectional stresses of the steel pipe support system are within the allowable values. This implies that the steel pipe support system can be effectively used as an alternative to conventional H-pile support system.
