SENSITIVITY OF STRUCTURES AND GEOLOGICAL DATA

Abstract eng:
The paper discusses the subgrade-structure sensitivity to uncertainties, ambiguities and scarcity of geological data, obtained and processed in the course of geological surveys. These aspects have mostly been neglected: two special in situ tests, staged in USA and in Russia, showed considerable soil data uncertainties and scatter even at nearby points. On the other hand, most structures are insensitive to many (not all) these uncertainties. So, a compromise between structure sensitivity and soil data uncertainties is an issue. Numerical simulation with the help of specially developed software showed some sensitivity evaluation results.
