Research on Axis Direction Selection for Underground Powerhouse of Pumped Storage Power Station Based on Block Theory
摘要
Abstract
The axis direction selection for the underground powerhouse of pumped storage power station is an important factor that affects the layout of the powerhouse and the stability of surrounding rock.In order to determine the appropriate axis direction of the underground powerhouse,the statistical analysis of the rock mass structural planes in the geological exploration adits of the underground powerhouse is conducted to identify the dominant structural planes;The relationship between the axis direction of the underground powerhouse and the net sliding force of the block is calculated and analyzed by using the block theory program;Combined with the layout of the water transmission and power generation system,the quantitative analysis of the stability of the random block in the cavern under the axis direction of the recommended underground powerhouse is carried out.It is the results that block stability problem composed of rock fissure structure and cavern excavation face is very small,the proposed axis direction of the cavern is appropriate.关键词
