Abstrakt: The chief objective of the article is to investigate the bearing capacity of limestone strata roof containing a shallow-buried cylinder Karst cave. Firstly, taking into account the characteristics of Karst landform in China, a spatial axial-symmetrical model was established. Concurrently, the general solution of stress components was gained using Love displacement method. Subsequently, combining failure mechanism of ground collapse and the expressions of stress components, the bearing capacity calculation formula was determined. Finally, based on practical engineering, a comparison of calculation result indicates the error is less than 3.5%, which meets the proposal standard necessity in practice. [ABSTRACT FROM AUTHOR]
