Given internal water load as a kind of body load, an axisymmetric thick-walled cylinder model is built, in which the nonuniformity coefficients of reinforcement strain and concrete strain are introduced to compute the lining's equivalent permeability coefficient. The water-filled joint element model is developed to simulate the limited cooperation between reinforced concrete lining and surrounding rock. And an equivalent method is adopted to develop the computer program. The reinforcement stress and the surrounding rock stresses are calculated in pervious pressure tunnel with internal water exosmosis. The results show that the reinforcement stress obtained by the new method is near the observed data in the practice project. The fact that the reinforcement stress is at a lower stress level in the pervious pressure tunnel with high internal water load is verified.
Keywords:hydraulic structure; pervious pressure tunnel; internal water exosmosis; interaction; cooperation; water-filled joint element
