Background
Due to the increasingly compact utilization of urban space, a great number of construction projects are occurring which are closely built along subway lines and around subway stations. Along with the gradual increase of the height of urban buildings, the influence of building loading on the lying tunnels is increased, so that the influence on surrounding running subways is unavoidable, and the subways are slowed down or even stopped when serious.
At present, few researches on deformation of surrounding tunnels caused by building engineering at home and abroad are focused on the influence of surrounding tunnels caused by excavation of foundation pits. Some scholars predict the displacement and stress change of surrounding soil and tunnel lining caused by foundation pit excavation through a numerical calculation method, and discuss the influence of different loads and different positions of a building structure. However, the numerical calculation method has obvious defects that a great deal of effort and time are required for modeling and calculation, proper constitutive relation and other factors are required to be considered, and the method is basically focused on the research of longitudinal deformation of a tunnel caused by excavation of a foundation pit. The analysis and calculation method is quicker, and the result can be obtained only by simply adjusting corresponding parameters for a few minutes when other conditions are changed except for time for the first time (but still faster than numerical simulation). At present, the conventional method for calculating the deformation of the cross section of the tunnel can only consider the natural load condition, but cannot consider the calculation under the additional load condition. Analytical calculation methods for deformation of the cross section of the lying tunnel caused by the building structure are not researched.
