Metro Line U5 in Berlin – design challenges due to complex geotechnical conditions / U‐Bahnlinie U5 in Berlin – besondere Herausforderungen für die Planung aufgrund der komplexen geotechnischen Gegebenheiten

A 2.2 km section of Berlin's Metro Line U5, currently under construction to connect existing underground structures between Berliner Rotes Rathaus and Brandenburger Tor stations, presents significant geotechnical challenges due to complex subsurface conditions. The project involves constructing three new stations—Rotes Rathaus, Museumsinsel, and Unter den Linden—with the Museumsinsel station requiring ground freezing techniques for stability during excavation. This innovative approach addresses the unique geological and urban constraints of the site, including its proximity to the River Spree, the planned New Berliner Schloss, and the historic Unter den Linden street. The study highlights the necessity of advanced geotechnical solutions in dense urban environments, particularly where historical preservation and modern infrastructure intersect.
