On the safe side, we should use active soil pressure and passive soil pressure to calculate the support strength before T increased. That is RA=EA-EP Among them: RA ………… holding strength EA ………… composite force of active soil pressure EP ………… composite force of passive soil pressure Immediately, flexural torque distribution of enclosure wall can be counted. Mmax is the location of shear force zero. Equivalence beam method abridges. No matter which kind of supporting structure form, the key problem lies in the establishment depth of catch point, severity of support and enclosure wall, penetration depth and pit bottom quality of soil property.
