Study on Stability of Shield Tunnel Excavation Face in Soil-Rock Composite Stratum

In order to study the instability mode of shield excavation face in soil-rock composite stratum and determine the ultimate support pressure of excavation face, this paper selects two typical soil-rock composite strata and uses three-dimensional finite element software to study the failure developmen...
