Abstract: The two-dimensional elastic model for the analysis of the ground surface subsidence due to shallow tunnel excavation is established based on elastic mechanics theory. And the theoretical formula of ground surface subsidence due to shallow tunnel excavation in soft soil strata is given and is applied to the analysis of ground subsidence due to shallow tunnel excavation in soft soil strata. The Matlab is used to solve the calculation of the numerical integration and drawing of the figure in the course of the analysis. The agreement of the theoretical results with the field measurements shows that the model is satisfactory.
