| Abstract: | In Sichuan Red Basin,excavating cuttings in gently inclined red beds composed of sandstone and mudstone intercalations,mudstone would be indented inward by weathering,and result in a niche on the slope surface.slope,and the bearing force of the support structure must computed in design.In this paper,the overlying sandstone bed is regarded as cantiever beam,and a calculation method for the bearing force is developed,A calculation example is also given. |
