What is Yielding elements – requirements, overview and comparison about?
## Abstract Large deformations are usual for tunnel excavation in weak rock mass and high overburden. In order to avoid overloading the support, various ductile support systems have been developed in the last 15 years to permit the controlled build‐up of load in the lining. The design of such a ductile support system requires the consideration of the development of displacements in space and time, the time‐dependent properties of the shotcrete and the characteristics of the ductile elements. The requirements for a yielding system are described. The latest developments in yielding elements for use with shotcrete support are discussed and their general performance and effectiveness are explained. Bei Tunnelvortrieben in Gebirge geringer Qualität und hoher Überlagerung treten in der Regel große Verformungen auf. Zur Vermeidung einer Überbeanspruchung des Ausbaus wurden in den letzten 15 Jahren unterschiedliche duktile Ausbausysteme entwickelt, die einen kontrollierten Lastaufbau in der Auskleidung erlauben. Zur Auslegung eines solchen duktilen Ausbaus müssen die räumliche und zeitliche Entwicklung der Verschiebungen sowie die zeitabhängigen Eigenschaften des Spritzbetons und die Chara
