RISK-BASED LIFE CYCLE MIM STRATEGY FOR COASTAL STRUCTURES – EFFECT OF PRE-EXISTING DAMAGES ON FAILURE PROBABILITY –

[摘要] A risk-based strategy for monitoring, inspection and maintenance (MIM) is described as a key component of an overall framework for life-cycle engineering and management. Its application for coastal structures is exemplarily outlined for sea/estuary dikes and harbor quay walls. The necessity of the incorporation of pre-existing damages into this strategy is exemplarily illustrated for quay walls, showing how this will affect the failure probability in comparison to a quay wall without any pre-existing damages.
