Differential weathering overhanging rock by hard rock and soft rock interlayer is common for geological failure.To study the influence of ground stress in rock slope and cave deepness to differential weathering overhanging rock
a mechanical model was proposed.And hollow cylinder stress meter was used to test and analyze onsite ground stress at Hongyadong in Chongqing.Moreover
the development range of overhanging rock was determined.And a case studywas used to analyze the relationship among tension ground stress
cave deepness and growth of controlling crack.A method for forecasting overhanging rock failure pattern was proposed.
