Abstract

The numerical simulation study for water conveyance of penstock laid on downstream surface of overfall dam on water security is of great significance. Static analysis of penstock laid on downstream surface of overfall dam is the foundation of design and construction, includes the calculation and analysis of stress and strain of penstock laid on downstream surface of overfall dam. Using the nonlinear finite element theory and taking the penstock laid on downstream surface of overfall dam of Longtan Hydropower Station for the study,the inner surface of the cushion is defined as the goal face,using the outer surface of the steel liner tubet to the face contact and using the contact element to simulate the contact conditions between the steel liner pipe and the surrounding concrete at the same time we should take constitutive relations between the steel liner and concrete nonlinear into account and research the distribution of stress and deformation of the pressure pipe.
