| Abstract: | The underground powerhouse of a certain hydropower station has larger scale with the largest span of 31.10 m and the maximum height of 78.0 m in southwest China.The geological conditions of underground powerhouse are special and belong to the high field stress areas.During the process of excavation,the upper boundary wall of the powerhouse appears some phenomenon that the rate of stage deformation is faster and the convergence of time-displacement curve is unobvious.Combined with similar projects,the paper ... |
