Detailed engineering geological investigations have been completed on Lingquan Temple Grotto
in Henan province. The Grotto that was constructed about 1
400 years ago and consist mainly of hard compact crystalline limestone has produced serious geological diseases . A classification of the geological diseases is carried out in the present paper
they are: rock mass instability
water percolation and corrosion
and weathering diseases . Moreover
the reasons for the diseases are analyzed . The safety factor of the rock mass and the slope have been obtained respectively through analytical method and finite element method by assuming the seismic loading being pseudostatic. Finally
