EVALUATION OF SIMULTANEOUS FAILURE PROBABILITY FOR TWO QUAY WALLS IN DIFFERENT SITE CONSIDERING THE DISTANCE
A method to evaluate the failure probability of a quay wall under the condition that another quay wall was damaged by the earthquake is proposed. The shorter the distance of the two quay walls, the stronger correlation on the failure probability exists. And the simultaneous failure probability shall be increased. This is dependent not only on the locations of the two quay walls, but also on the locations of the faults. However, a simple parametric study enables to consider the correlation of failure probability at two sites. Thus the simultaneous failure probability of two quay walls can be evaluated using the proposed method. And the evaluated simultaneous failure probability can be a key index of port planning to avoid the disastrous situation such as the whole quay wall was damaged. As a conclusion, a simple procedure to evaluate the simultaneous failure of two quay walls was summarized to enable an efficient arrangement of earthquake-resistant quay walls comprehensively.
