Abstract

Ensuring the safety and excavation efficiency of pumped storage power stations (PSPs) requires a focus on stability in the construction and design of underground cavern groups, along with the implementation of intelligent safety analysis and warning systems. This paper primarily focuses on the application of this system in Tiantai PSPs and highlights stability issues that may arise from uncertainties like joint fractures or poor rock conditions resulting in untimely support during construction. To accurately measure rock mass mechanics parameters, the paper recommends utilizing various mechanical responses of surrounding rocks and employing inverse analysis techniques for material parameter inversion. Additionally, the paper examines the deformation and stability effects caused by different factors such as lagged support and geological conditions through a case study that demonstrate support reinforcement practices at the powerhouse end. The paper also discusses suggested measures for dealing with these issues. Ultimately, this approach helps ensure both the safety and efficiency of the construction and operation of underground caverns while minimizing potential environmental and community impact.
