Abstract

In subway engineering construction, the soil between the subway station and the auxiliary structure is considered a confined space. Therefore, it is not appropriate to calculate by Ranking and Coulomb’s classical earth pressure theory. A theoretical calculation method for earth pressure on limited soils is established based on the horizontal stratified microcloud method. This method involves creating a mechanical model and taking into account the various overlying loads and bilateral contacts. It provides a reliable reference for the design of subway foundation pit supporting structures. Further analysis of parameter influence shows that increasing the width of the soil, decreasing the internal frictional angle of the soil, and increasing the interface frictional angle will result in an increase in earth pressure for confined soils. Additionally, it is observed that the width of the soil has the most significant impact on the earth pressure for confined soils. The earth pressure for limited soils is distributed in an arched shape along the depth. The earth pressure for limited soils in smaller soil action areas increases with depth.
