Abstract

The steel lined reinforced concrete pressure penstock is a new kind of structure design form. Lots of structural model test results and prototype observation data indicate that under initial water pressure stress, the steel lining and outer wrapped concrete shell can work with the good joint, joint bearing. The paper uses general finite element calculation software to do the nonlinear analysis for steel lined reinforced concrete penstock of manwan hydropower station and study three kinds principles: the change principle of the stress of steel lining arising along with the increasing of internal pressure, the elastic-plastic distribution principle of outer wrapped concrete and the crack development principle of concrete. The analysis results indicate that the design project of the steel lined reinforced concrete pressure penstock of manwan hydropower station is reasonable. The structure meets the requirements of strength, which pressure penstock structure will not crack, under the design load. Pressure penstocks meet the requirements of stiffness, that the transformation is small. The structure design is economic and reasonable, safe and reliable.
