Features: This book takes the design concept of joint load-bearing between the lining and surrounding rock of hydraulic pressure tunnels as its main thread. On the basis of comprehensively elaborating the structural design principles of hydraulic pressure tunnels, it introduces the calculation of surrounding rock stress for unslined hydraulic pressure tunnels, the calculation of structural stress for lined hydraulic pressure tunnels, the calculation of resistance coefficient of surrounding rock in pressure tunnels, the calculation of stress for lined surrounding rock with water content, the calculation of temperature stress in pressure tunnels, the calculation of grout-prestressed lining, and the finite ring displacement coordination analytical method for crack-limited design of concrete lining in pressure tunnels, deriving the corresponding analytical calculation formulas. The book provides a general calculation formula for the resistance coefficient of surrounding rock in hydraulic pressure tunnels, based on the established calculation method and analytical formula for the development width of hydraulic pressure tunnels. Additionally, it employs fracture mechanics theory to derive the crack-limited design formula for reinforced concrete lining in tunnels. To facilitate readers' deeper understanding of the content in each chapter, worked examples are provided for every chapter. This book is suitable for engineering design personnel and scientific researchers in water conservancy, hydropower, railways, mines, and related fields, as well as for faculty and students of relevant universities.
