Features: This book takes the design concept of joint load-bearing between hydraulic pressure tunnel lining and surrounding rock as its main thread. On the basis of comprehensively elaborating the design principles of hydraulic pressure tunnel structures, it introduces the calculation of surrounding rock stress for unsurfaced 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 lining stress in water-bearing surrounding rock, the calculation of temperature stress in pressure tunnels, the calculation of grout pre-stressed lining, and the finite ring displacement coordination analytical method for limited crack design of concrete lining in pressure tunnels, and derives 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. The book also uses fracture mechanics theory to derive the limited crack design formula for reinforced concrete lining in tunnels. For the convenience of readers to deepen their understanding of the content of each chapter, examples are provided in each chapter. This book can be used by engineering design personnel and scientific research personnel in water conservancy, hydropower, railways, mines, and other fields, and can also be used as a reference for teachers and students of relevant universities. ... Based on the elaboration of the design principles of hydraulic pressure tunnel structures, the book introduces the calculation of surrounding rock stress for unsurfaced hydraulic pressure tunnels, the calculation of structural stress for lined hydraulic pressure tunnels, and the calculation of resistance coefficient of surrounding rock in pressure tunnels, among other content.
