Analyse on the deformation stability of surrounding rocks of the undergroud factory building chamber group at Dagangmountain hvdrooower station of Dadu river

摘要：

The underground factory building chamber group of Dagangmountain hydropower station is on the left side of Dadu River with the character of huge scale and complex geology situation. This paper gets beginning at the engineering geological conditions of the research area with determining the surrounding rock classifications, uses the two-dimensional finite elements to re-calculation the natural stress on the purpose of imitation actual stress distribution in this area. Then this paper gets further imitation on the stress and deformation regulation that based at excavation. The imitation of the regulation should have some important affecting during engineering construction.
