Abstract
Support systems in urban areas for temporary excavations are necessary to keep the sides of excavation nearly vertical, to minimize the excavation area and to ensure that the excavation is stable from stability as well as deformation criteria and will not lead to any damages in the surrounding area. In the present study, the paper discusses the cause for the failure of excavation of 11.65 m deep supported by nailing. The serviceability requirements and factors of safety are evaluated using finite element analysis. Further, it discusses the revised design for a temporary support system. The paper highlights the importance of pull out tests in the preliminary stage as well as during execution which are useful in design and performance assessment of the shoring system. The revised system is implemented in the field and is performing well.
