THREE DIMENSIONAL NUMERICAL SIMULATION OF UNDERGROUND ROCK EXCAVATION IN MAYA ROCK SLOPE FOR SHUIBUYA HYDROPOWER PROJECT

D numerical simulation of underground excavation in high rock slope with software Rocky was carried out for study of Maya rock slope engineering related to Shuibuya hydroelect power project. The numerical simulation of mechanical situation and rock pillar stability of tunnel engineering in the slope and slope cuting measures for the stability control are illustrated in detail. These studies also consist of earthquake dynamic simulation of slope engineering in practice. The numerical simulation result shows that the study is reasonable and practical.
