| Abstract: | Based on the bedding features of weak intercalations in sandstone plates near the top of underground cavity,the probable failure scale of bedding sliding,the probable settlement,the folding places and the critical length of sandstone beams are computed seperately,then the stability of underground cavity is analysed. |

| Keywords: | weak intercalation stability |
