Zusammenfassung: | The utility model discloses an internal force adjusting structure of an arched foundation pit supporting system. The structure comprises an arched foundation pit supporting system and a prestressed tie bar cable, the arch foundation pit supporting system comprises an arch ring and an arch support. The prestressed tie-bar cable is arranged at the top end of the skewback. The prestressed tie bar cable is arranged at the arch seat of the arch foundation pit supporting system, the horizontal thrust of the arch supporting system is balanced by tensioning the tie bar cable, the displacement of the arch crown of the foundation pit in the tangential direction of the arch seat is restrained, and the effects of optimizing a structural stress system, reducing the size of the section of the arch seat and improving the safety and stability of the foundation pit system are achieved.
