With growing urbanization, an increasing number of landslides worldwide are linked to construction works, especially along transportation routes. To get a better understanding of these post‐construction landslides at artificial waterways, archive studies have been conducted, in addition to analysis of historical scientific literature and technical reports. The resultant database is used to describe the occurrence and the characteristics of the landslides at the Mittelland Canal, and to evaluate aspects of conditioning and preparatory factors, potential triggers and applied mitigation measures. The Mittelland Canal has been chosen because it is one of the most important artificial waterways in Europe, and the high number of landslides that occur there is unique. In particular, landslides at the Mittelland Canal were frequently reported in the first half of the 20th century. The susceptibility to landslides is strongly influenced by material characteristics, as a large number of landslides is linked to sites where fine‐grained mudstone is abundant, which quickly decomposes under immersion in water or under dynamic stress. In addition, landslides can be linked to the creation of over‐steepened slopes. Construction works can also be considered another preparatory factor for landslides. In addition, some landslides in World War II appear to be connected to the blast of aerial bombings. Precipitation seems to play a minor role in triggering landslides. The applied mitigation measures were developed recently, marking the importance of the canal as a transportation route. © 2020 John Wiley & Sons, Ltd.

分析历史数据,以更好地了解人工水道施工后的滑坡

随着城市化的发展,世界范围内越来越多的滑坡与建筑工程有关,特别是沿运输路线。为了更好地了解人工水道上的这些建设后滑坡,除了对历史科学文献和技术报告进行分析之外,还进行了档案研究。结果数据库用于描述米特尔兰运河上滑坡的发生和特征,并评估条件和准备因素,潜在诱因和应用的缓解措施等方面。选择米特尔兰运河是因为它是欧洲最重要的人工水道之一,并且那里发生的大量滑坡是独一无二的。特别是,世纪。滑坡的敏感性受材料特征的强烈影响,因为大量的滑坡与细粒泥岩含量丰富的地点有关,这些泥岩在浸入水中或在动态应力下会迅速分解。此外,滑坡可能与过度陡峭的斜坡的产生有关。建设工程也可以被认为是滑坡的另一个准备因素。此外,第二次世界大战中的一些山体滑坡似乎与空中炸弹爆炸有关。降水似乎在引发滑坡中起很小的作用。最近开发了应用的缓解措施,标志着运河作为运输路线的重要性。分级为4 +©2020 John Wiley&Sons,Ltd.
