摘要：
The present study discusses the structural response of a parent tunnel when a near circular breakout is made for a perpendicular child tunnel. Beyond the presentation of some main background on the topic, the description of the investigated systems and the investigation methods is provided, this mainly being linear-elastic finite elements analysis, with inclusion of analytical solutions for comparison and with some analysis assuming non-linear soil behavior in order to investigate particular aspects in the discussed systems. This paper contributes to the little hitherto available literature with respect to the soil structure-interaction and the structural behavior at tunnel breakouts and junctions, while reference for future projects is offered through 36 analyzed cases.
