three-dimensional evaluation of land settlement resulting from subway tunnel excavation using numerical method (case study: qom)

Today, with the increasing population in urban areas, one of the main concerns is the limited usability of land. this lack of surface space has led to the development of underground structures for water and sewerage and transportation network, especially the construction of subway tunnels. it is generally unavoidable to build such tunnels in the vicinity of deep foundation buildings. therefore, predicting the amount of settlement of the ground resulting from tunnel excavation to prevent damage to surface and deep structures, as well as the foundations of buildings and sensitive structures around it and its control is one of the most important issues that must be considered before drilling operations. therefore, control of surface settlements and other environmental impacts is a key issue for designing tunnel drilling projects. one of the effective factors in the amount of land settlement resulting from drilling is the geomechanical properties of the soil mass including tunnels, dimensions and geometric arrangement of tunnels, which has a great effect on the maximum amount of land settlement and the shape of the curve to the shape of the earth by the researcher. have not been reviewed. accordingly, in the present study, a number of numerical analysis modeling using 3d analysis in abacus finite element software was performed to investigate the surface settlement resulting from the construction and excavation of subway tunnels in urban areas and the effect of tunnel depth and diameter parameter on settlement in drilling. the tunnel is discussed in detail in the new austrian method.
