Description:
In mollisol subsurface excavation, the selection of the vertical load of utility tunnel will directly affect the economy and safety of the project. It is necessary to consider the effect of soil arch on the design of the integrated excavated tunnel in the mollisol stratum, which is related to the value of vertical load. From the aspects of stress field variation and inhomogeneous deformation, to obtain the results of the influencing factor, buried depth, we analyzed the action mechanism of soil arch pressure. In mollisol subsurface excavation of utility tunnel, the deeper buried depth, the more obvious the arch effect is. The influence of buried depth on the arch effect in mollisol has certain guiding significance for the value of vertical load of mollisol tunnel, which can provide the basis for the design of integrated utility tunnel.
