Abstract

A quay wall directly next to a building, both dating around 1870, collapsed along the Grimburgwal in Amsterdam on September 1, 2020. The historic quay wall consisted of a masonry wall, built of a timber deck supported by several rows of timber piles of about 12 m long. As over 200 km of such quays exist in Amsterdam, and streets are usually very busy, the collapse triggered the question of the safety of the remaining quay walls in the city. A forensic investigation was carried out to determine the failure mechanisms and factors that contributed to the collapse. The investigation aimed to learn from this event and to prevent similar failures in the future. The main failure mechanisms and contributing factors were identified and confirmed using an integrated model of the quay, which is both simple and robust. The model was used to perform a sensitivity study taking all relevant uncertain factors into account. This work provided valuable insight into the main collapse mechanisms of the wall. Based on the results of this forensic study it is possible to assess other historic quays.
阿姆斯特丹历史悠久的格里姆堡瓦尔码头的倒塌
2020年9月1日,阿姆斯特丹格里姆伯格瓦尔河沿岸的一堵码头墙倒塌,这两堵墙都建于1870年左右。历史悠久的码头墙由砖石墙组成,由几排约12米长的木桩支撑的木材甲板组成。由于阿姆斯特丹有超过200公里的这样的码头,街道通常非常繁忙,因此倒塌引发了城市中剩余码头墙的安全问题。进行了法医调查,以确定导致倒塌的失效机制和因素。调查的目的是从这次事件中吸取教训,防止今后发生类似的事故。采用简单、鲁棒的综合模型,识别并确定了码头的主要破坏机制和影响因素。该模型用于考虑所有相关不确定因素的敏感性研究。这项工作对墙的主要坍塌机制提供了有价值的见解。根据这项法医研究的结果,可以评估其他历史悠久的码头。
