Geotechnical Risk and Reliability from Theory to Practice

Indeterminate combined with evaluating the safety of existing lifeline systems are, large and here one would expect format risk and reliability techniques to have found their most urgent need. Besides, risk analysis has languished in safety practice, is only now beginning to appear in established safety programs in my country. It is of interest to explore the reasons why this has been so, and to point the way to the adaptations that are necessary if risk analysis is to assume its deserved role in life-line systems and related areas of geotechnical practice. This paper has proposed that geotechnical conditions are needed to enable more reliable predictions of performance in practical. The main problem can be establish finally to the fundamental differences in approach between engineering science and engineering practice. In discussing these differences Peck (1979) described how science reasons from first principles based on laboratory behavior and analysis, while field performance data and empirical methods provide the basis for practice
