Abstract

In recent years, due to the advantages of soil nail which can be constructed in areas with difficult access and minimizes earthwork, soil nail system has also demonstrated its applicability for deep excavation works. The use of soil nail system has resulted in cost saving to deep excavation project and also enables basement construction to be carried out in a relatively unobstructed work space. Therefore it becomes necessary to study the applications of soil nail wall in excavation since it provides straight forward construction method and is relatively maintenance free. Comparisons of RCC Retaining Wall with soil nail wall gives a clear idea about the performance of both when used to retain the vertical cut. A static and dynamic analysis is carried out for 6m and 8m height retaining wall and soil nail wall which is numerically simulated in plaxis 8.2 then its global factor of safety, horizontal displacement, base heave comparison is carried out in this study.
