英文摘要 | Breakwaters are the most important port structure. They protect the port from the wave force caused by the wind or storms. However, the uncertainties of the wave pressure, friction coefficient, wave height, influence the safety of the deep breakwaters. It also affects the safety of the entire port. Based upon the mean-value-first-order-second-moment technique, a model of wave pressure on breakwaters is developed which incorporates the random wave pressure or the friction coefficient properties as well as the uncertainty of the wave force. The results show that the reliability of the sliding analysis of the east outer breakwaters in Keelung harbor are between 99.60% to 99.7% from 1983 to 1990. And the reliability of the overturning analysis is also above 99.5% from 1983 to 1990. In a similar manner the reliability of the sliding and overturning in the storm were also analyzed and results are given. |
