Abstract

The formidable challenge confronted by engineers of this century is designing and construction of sustainable infrastructures that support civilization. Such modern structures in urban dwellings inevitably induces new deep excavations to be built close to existing piled foundations. In order to assess this interaction and to cope the practical challenges faced during construction, thus far there have been numerous researches and advances in experience. The remarkable evolution took place over the decades in the deep excavation technology and other relevant technologies has been well detailed in the literature but needs refinement in considering the complex nonlinear stress-strain response of soils corresponding to different unloading effects (stress-path dependent soil deformation) while analyzing the effect of excavation on the nearby pile foundation. Moreover, it is observed that previous experimental studies performed to simulate the problem did not fully take into account the effect of embedded pile caps, excavation supporting structure installation and superstructure stiffness.
