摘要: Reliability analysis of the buried flexible pipe-soil system is performed from three different failure criteria: (1) deflection; (2) buckling; and (3) wall thrust. The response surface methodology used to establish approximate functional relationships between input variables output responses reliability using first-order method approach. available analytical solutions as well results numerical are in discussed. A comparison light deterministic indicated that probabilistic approach, which considers variability parameters provides a means understanding performance system.
