Reliability Analysis of Wing Wall Tunnel Portal

  • Publish Date: 25 Oct 2002
  • According to the structure reliability theory and considering the indefinite factors such as the stratum unit weight, the subbase friction coefficient, the base control press stress, the concrete unit weight, etc. a reliability analysis of wing wall tunnel portal structure is made by use of one- order-two-moment method. The computation results show that the computation model is connected with reliability indexes and the reliability indexes meet the requirement on the whole.
