Safety Evaluation of Adjoining Structures in Urban Areas During Deep Excavation: A Case Study of Nagpur Metro
Construction in congested urban areas has necessitated tall and massive structures. In urban areas, it is common to construct underground structure nearby existing buildings. Selection of an appropriate support structure system to be implemented in the excavation in an urban area is heavily dependent upon the geotechnical conditions and safety of the surroundings and neighbouring structures. Urban Rail, popularly referred to as Metro Rail, has seen substantial growth in India in the recent years. More cities are experiencing the need for metro rail to meet their day-to-day mobility requirements. The metro structures involved deep excavation for foundations, which induces the stresses and thereby alters the existing equilibrium and thus may affect the stability of neighbouring structures considering safety point of view. Hence, design and execution of deep excavations become one of the important challenging tasks of any geotechnical engineer in the modern era. Further, it is important to control the ground movement in order to prevent the failure of excavations. This involves specialized foundation technologies, usage of sophisticated equipment and new methods in underground construction, safety and monitoring systems. In this paper, the methodology used for protecting adjoining structures due to deep excavation for Nagpur Metro station is studied.
