A　general　framework　for　probabilistic　damage　in　rock　using　maximum　entropy　theory　is　proposed　to　describe　the　failure　process　of　marble　from　hydropower　station　at　Jinping　II,　China.　In　this　paper,　the　failure　process　of　marble　is　divided　into　three　stages.　In　the　first　stage,　a　parameter　D0　is　employed　to　describe　the　compaction　of　rock　before　elastic　period　which　can　be　calculated　by　maximum　entropy　theory.　In　the　second　stage,　elastic　theory　is　used　to　express　no　damage　in　the　rock.　In　the　last　stage,　a　parameter　D　is　performed　to　define　and　calculate　the　damage　of　rock　based　on　maximum　entropy　theory.　The　proposed　model　is　used　to　simulate　the　failure　process　of　marble　under　uniaxial　compression.　The　simulated　result　is　well　agreement　with　experimental　data,　validating　the　proposed　computational　framework.　©　2015　Taylor　&　Francis　Group,　London.
