Abstract: Brückenbauwerke im alpinen Raum unterliegen verschiedenen Naturgefahren. Dazu zählen auch Muren. Murenereignisse führen nachweisbar auch zur Zerstörung von Brücken. Um Brücken für solche Einwirkungen zu bemessen, sind Angaben zur Anprallkraft von Muren notwendig. Für Murenanpralle gegen Pfeiler liegen umfangreiche, sowohl miniaturisierte als auch Realgrößenversuche vor. Für Brückenüberbauten sind bisher keine solchen Versuche bekannt. In diesem Beitrag werden miniaturisierte Murenanprallversuche an Massivbrück… Show more

The construction of sustainable bridge projects has become a global mission and challenge in the 21st century. Unfortunately, there has been a rise in bridge collapse incidents due to various factors in recent years both during the construction and service phases. These incidents have resulted in significant loss of life and property damage, exacerbating the five sustainable development issues faced by bridge engineering: natural, resource, environmental, social, and economic factors. As a result, the prevention and resolution of bridge collapse accidents have garnered attention from professionals, research institutions, and government departments, making it a prominent research area. In line with the sustainable development concept of bridge engineering, this article classifies the causes of bridge collapses into two categories: those occurring during the construction phase and those happening during the service phase; the latter includes lack of inspection, maintenance and management, external natural factors, and human factors. Furthermore, this article thoroughly examines the existing national management framework, identifying the dilemmas that hinder its effectiveness in regulating bridge collapse prevention. Finally, several effective suggestions are proposed for the prevention of bridge collapse incidents. These recommendations aim to motivate governments, project owners, designers, constructors, managers, and users to actively develop and promote high-quality sustainable bridges.
