In this contribution observed median collapse frequencies and calculated median failure probabilities of retaining structures are compared. Such comparisons have already been carried out for bridges, dams, tunnels, buildings, stadiums and wind turbines. The comparison is carried out as a meta-analysis using values from the literature. Furthermore, collapse frequencies due to earthquakes were determined by the authors’ own calculations. The comparison of median collapse frequencies and median failure probabilities of retaining structures shows a good agreement. The ratio of the median failure probability and the median collapse frequency is in the range of other engineering structures. However, the comparison with other engineering structures shows an above-average frequency of collapses. This seemingly accepted high frequency of collapse appears to be justified by the lower number of victims and lower damage costs when retaining structures fail.

支挡结构的倒塌频率和失效概率

在这篇文章中，比较了观察到的中值倒塌频率和计算出的支护结构的中值失效概率。已经对桥梁、水坝、隧道、建筑物、体育场馆和风力涡轮机进行了此类比较。使用文献中的值作为荟萃分析进行比较。此外，地震引起的倒塌频率是由作者自己计算得出的。挡土结构的中值倒塌频率和中值失效概率的比较显示出良好的一致性。中值失效概率与中值倒塌频率之比在其他工程结构的范围内。然而，与其他工程结构的比较显示倒塌频率高于平均水平。
