Abstract: In order to have a clear understanding for the mechanical mechanism and cracking rules of steel lined reinforced concrete penstock laid on downstream surface of dam, this paper adopts nonlinear finite element theory to carry out force analysis. The research object of the paper chooses steel lined reinforced concrete penstock laid on downstream surface of dam for Longkaikou Hydropower Station, and a nonlinear finite element calculation model is built by the finite element software. Research results show that when the internal water pressure is smaller, the steel lined bears full load, when the internal water pressure increases to a certain value, the steel lined and reinforced concrete pipes bear the load jointly. With the increase of internal water pressure, the circumferential stress and radial stress of the steel lined and reinforced concrete pipes increase obviously, the bearing ratio of reinforced concrete pipe is gradually increasing, but the growth of bearing ratio is small. When the internal water pressure gradually increases, the circumferential stress value is significantly greater than the radial stress value, normally tensile damage along the radius direction of the reinforced concrete pipe happens.
