| Abstract: | 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, suggestions are given for renovating the Grotto. |
