Abstract :

Today, the demand for underground spaces rises due to the vertical growth of cities. Excavation operations for constructing car parking in residential and commercial buildings are an example of creating such spaces. The assurance of excavation stability by the aid of different systems is of high importance in temporary excavation operations in urban areas. Nailing stabilization, used to stabilize excavations, is the area of focus nowadays. Conventionally, soil nailing and the analysis of excavation performance are executed as overload analysis where the direct effect of buildings adjacent to the excavation is not taken into account. Therefore, this study aimed to evaluate the mutual effect of excavations and buildings using ABAQUS. This study used three different buildings with different foundations: a 2-story building, a 5-story building and an 8-story building. The results indicated that as the number of stories increases, the lateral displacement of excavation and the subsidence of adjacent earth increase. Moreover, it was concluded that piles decrease the lateral displacement of excavation wall and subsidence so that in the presence of disconnected and connected piles, lateral displacement decreased by 45% and 50%, respectively and subsidence decreased by 38%.
