Bearing capacity of soil foundations subject to metro facilities (for example, the ventilation tunnel)
The increasing density of urban development, along with active development of underground space, leads to the need for a detailed accounting of the mutual influence of foundations of existing (designed) structures with slightly deepened underground facilities for various purposes. Mainly, it is important to consider the impact of underground structures on the bearing capacity of the Foundation soil. For this purpose, the author used methods of the theory of limit equilibrium of soils. The solution of the problem under consideration is shown by the example of the influence of the ventilation tunnel of the subway on the bearing capacity of the Foundation soil. In the course of the research the regularities of changes in bearing capacity of Foundation depending on soil characteristics, location of the tunnel and its size. For the effective solution of the problem considered, the design of the specific sites proposed apparatus "lines of influence". The article presents practical guidelines for determining limit loads on the Foundation structure. Special attention is paid to verification used for the numerical calculations of bearing capacity of Foundation software package. Qualitative and quantitative analysis of the plots of the limit pressure at the base of the Foundation proves the necessity of considering whether the base of the underground facilities.
