Estimation of reliability of interaction foundation-ground systems

Abstract

For the modelling "foundation-statistically inhomogeneous ground" system's interaction, asymptotic analogies of Green's function have been constructed in Kasumov & Sobolev (1991). In this paper given application of above mentioned method for the probabilistic design of absolute rigidity plates resting on continuous statistically inhomogeneous ground and discrete elastic supports. The mechanical Winkler Model of the ground taken with random rigidity characteristics. Reliability of examine system estimated using fixed level (outcrossing) method. Numerical examples applied, result explanation. In brought numerical examples on each step of iterations, qualitative influence (in percentage) rigidity characteristics of discrete support (piles) and continuous basis to the reliability of system will be proceeded in an obvious kind. It makes flexible process of designing of researched systems. Many structure designs - roads spread on weak ground, anchorage of sea floating drilling platforms and so on Kasumov (1990, 91, 99)-at research of interaction of structure-foundation-ground system contain the analysed model (settlement circuit).
