BEHAVIOR OF SOIL NAILED WALLS UNDER CYCLIC DYNAMIC LOADS WITH FINITE ELEMENT METHOD, CASE STUDY

Soil nailing is a very versatile excavation retaining system suitable for deep excavations in urban areas surrounded by major structures. In this study the behaviour of a deep excavation of a huge structure in the East of Tehran that stabilized by combination methods of nailing and anchoring system has been studied. Soil nail wall used on this projects are subjected to harmonic dynamic loads due to heavy machinery and industrial plants nearby soil nail wall. The behavior of soil nail wall is investigated in the following sections with respect to the variations frequency. Effects of the pretention force in anchors on the maximum displacement and effects of the amplitude on the maximum displacement are evaluated.
