SENSITIVITY STUDY ON THE EFFECT OF THE SEEPAGE OF UNDERGROUND HYDRAULIC TUNNEL

摘要：

The seepage effect induced by high internal water pressure is unclear.The seepage-stress coupling analysis is used to investigate the influence of the seepage based on the Blots consolidation theory and the entity mixed model,in which the variation of steel stress is used to represent the change of stress state in the structure.Then sensitivity analysis is carried out to investigate the maximum of water pressure acting on the exterior surface of tunnel liner considering influencing factors including the crack width in reinforced concrete liner,the permeability of surrounding rock and the occurrence of structural plane in rock mass.
