The underground powerhouse of Henan Wuyue Pumped Storage Power Station has a complex structure of caverns. The main powerhouse has a maximum span of 26.0 m and a height of 55.1 m, which is a large underground chamber. The rock mass structural planes are developed and the strength is low. The fault F1 runs through the three powerhouse, and the safety problems are prominent. The stability of surrounding rock after excavation should be analyzed. Therefore, FLAC3D program was used to establish the geological model. The BSA-BP neural network was used to calculate the initial in-situ stress field of the area. And then the excavation of underground powerhouse was simulated. The stress field, displacement field and plastic zone development and distribution law of surrounding rock were analyzed. The results show that the surrounding rock of underground powerhouse caverns group is basically stable. However, local deformation and failure may occur in the fault development area and at both ends of the busbar hole. The research results can provide guidance for the design and construction of the project, and provide some reference for similar projects.

河南五岳抽水蓄能电站地下厂房洞室群结构复杂,主厂房最大跨度26.0 m,高55.1 m,为大型地下洞室。岩体结构面发育,强度低,断层f1贯穿三大厂房,安全问题突出,需分析其开挖后围岩的稳定性。为此,使用FLAC3D程序建立地质模型,采用BSA-BP神经网络反演计算了该区的初始地应力场,而后进行地下厂房开挖的模拟计算,分析了围岩应力场、位移场及塑性区发育分布规律,结果表明地下厂房洞室群围岩基本稳定,但在断层发育部位及母线洞两端存在局部变形破坏的可能。研究成果可为该工程设计、施工提供指导,也可为同类工程提供参考。

河南五岳抽水蓄能电站地下厂房洞室群结构复杂,主厂房最大跨度26.0 m,高55.1 m,为大型地下洞室。岩体结构面发育,强度低,断层f1贯穿三大厂房,安全问题突出,需分析其开挖后围岩的稳定性。为此,使用FLAC3D程序建立地质模型,采用BSA-BP神经网络反演计算了该区的初始地应力场,而后进行地下厂房开挖的模拟计算,分析了围岩应力场、位移场及塑性区发育分布规律,结果表明地下厂房洞室群围岩基本稳定,但在断层发育部位及母线洞两端存在局部变形破坏的可能。研究成果可为该工程设计、施工提供指导,也可为同类工程提供参考。

The underground powerhouse of Henan Wuyue Pumped Storage Power Station has a complex structure of caverns. The main powerhouse has a maximum span of 26.0 m and a height of 55.1 m, which is a large underground chamber. The rock mass structural planes are developed and the strength is low. The fault F1 runs through the three powerhouse, and the safety problems are prominent. The stability of surrounding rock after excavation should be analyzed. Therefore, FLAC3D program was used to establish the geological model. The BSA-BP neural network was used to calculate the initial in-situ stress field of the area. And then the excavation of underground powerhouse was simulated. The stress field, displacement field and plastic zone development and distribution law of surrounding rock were analyzed. The results show that the surrounding rock of underground powerhouse caverns group is basically stable. However, local deformation and failure may occur in the fault development area and at both ends of the busbar hole. The research results can provide guidance for the design and construction of the project, and provide some reference for similar projects.
