SEISMIC PIPELINE-SOIL INTERACTION UNDER UNCERTAIN-BUT-BOUNDED INPUT PARAMETERS: A STOCHASTIC NUMERICAL APPROACH
Апстракт
The unilateral contact problem of dynamic soil-pipeline interaction under uncertainty
concerning input parameters is treated numerically by a computational stochastic approach.
Unilateral contact effects due to tensionless soil capacity, soil elastoplastic-fracturing
behaviour and gapping are strictly taken into account, as well as environmental effects
decreasing the soil resistance. The proposed methodology concerns the treatment of both,
the deterministic and the probabilistic problem. The numerical approach concerning the
deterministic problem is based on a double discretization, in space by the Finite Element
Method combined with Boundary Element Method, and in time, and on nonconvex
optimization. Uncertainties concerning the input parameter values are treated as bounded by
upper and lower bound estimates using the Monte Carlo method in the probabilistic
problem section. Finally, the proposed methodology is applied for a practical case of
seismic soil-pipeline interacti...on.
