Excavation Methods, Strut, Deep Soil Mixing, Finite Elements


 Today, the increasing growth of urban construction as a result of urban development necessitates deep excavation in highly dense urban areas, therefore, supporting and securing excavation by appropriate methods have become of crucial importance. In such conditions, common and widely used methods of excavation support will be used by designing engineers. However, each of these methods has its own disadvantages and limitations. Therefore, these methods cannot be used in various conditions with different geotechnical and site properties. In such cases, an accurate analysis of the condition can help the engineers to select and design the supporting and stabilizing system. In this regard, different methods have been used by engineers, among which numerical methods have led to appropriate results. In this study, a series of numerical analyses by the finite element code PLAXIS2D was used for investigating the behavior of an excavated zone in the central region of Ahvaz which has complicated geotechnical and site features. For this purpose, four different and common methods of excavation support including tangent piles with anchorage, a deep soil mixing system with anchorage, tangent piles with struts, and a deep mixing system with struts were examined. The results clearly showed that tangent piles with strutsgavethe best results due to the rigid-like behavior of its components.
