随着铁路建设数量的增加,占地的现象进一步凸显出来。虽然在线路设计的过程中一定程度上考虑减少铁路建设用地的需求,将改建铁路大型铁路枢纽站临近区间的新增铁路线选择在既有营业铁路两侧作为新建线位置。但也导致了原有上跨铁路公路桥梁由于孔跨不满足新建线路位置关系,桥梁墩台占压了新建铁路线的线位,需要拆除重建。由于遇到类似桥梁拆除工程多次。故结合拆除工程探讨跨铁路营业线上跨桥拆除施工安全要点。 相似文献

The new railway bridge across the Donaukanal and the Winterhafen in Vienna. The load tests for the new Winterhafenbrücke performed on September 1, 2008 were the last steps in reconstruction of the railway connection between Donaulände und Donauuferbahn, which was destroyed in April 1945. With a length of 168 m this new single‐line railway bridge, which is designed as a two‐field continuous girder bridge, is the central link and the heart of the project. The bridge spans were realised by triangular trussed girder across the Donaukanal on the one hand and a trough bridge across the Winterhafen on the other. Design, manufacture and assembly of the steel bridge was carried out in different stages and constituted a great technical challenge. The completion of the entire project in September 2009 will be an essential contribution towards shifting commercial transport from the road to the environmentally friendly rail. 相似文献

The bridge across the Oberhafenkanal in Hamburg. The replacement of 4 steel railway bridges with a total steel construction weight of 4000 tons in the centre of Hamburg, which connect the central station of Hamburg with the south of Germany was a great challenge in bridge building. The central steel superstructure of the bridge, the Oberhafenbrücke, a five‐span truss continuous beam is special because it is a combined railway and road bridge. The railway travels on the upper deck between the upper chords whereas the road traffic travels on the lower deck between the truss. This superstructure crosses the Oberhafenkanal. The available time for the complete building process comprised of statics, design, manufacturing and assembly was only 14months. The end of this process was totally fixed because of the long‐time announced complete shutdown of the railway connections to the south and parts of the Hamburg central station between December 24th and December 31st, 2007. Despite the new definition of substantial design‐parameters (load models for road and railway, permanent bearing‐system, temporary bearing‐system after December 31st, 2007) and therefore a reduction of the available time by 4 months the task of building the new bridge was carried out successfully by the consortium comprised of Eiffel Deutschland Stahltechnologie GmbH, Bilfinger Berger AG ZN Hamburg and Jürgen Martens GmbH & Co. KG. 相似文献

In the early morning of January 17, 1995, an earthquake of magnitude 7.2 occurred, with its epicenter in Awaji Island, to the south of Kobe City located near Osaka City. It was later named the Hanshin-Awaji Earthquake. The earthquake left over 6,400 people dead and about 40,000 injured, completely destroying over 100,000 houses and buildings, causing about 300 fires, resulting in the suspension of such “lifelines” as city water, electricity, and gas supply, and halting transportation systems including road and railway traffic. It inflicted extensive damage not only on Kobe, but also on Osaka and other cities. In the light of destruction caused by the earthquake, in 1997, the Osaka Municipal Government, the Osaka City Regional Preparedness Plan, which includes citizen evacuation in the event of earthquake, construction of seismic-resistant facilities, and fire-fighting and other emergency activities. The original plan was prepared, on the basis of an inter-plate earthquake occurring beneath the Pacific Ocean. In addition to this hypothesis, the new plan also incorporates the assumption that an earthquake with its epicenter under Osaka could occur due to movement of the Uemachi Faults running under the central part of the City in the north-south direction. Estimated damage that could be incurred through this potential earthquake were used for the latter plan. 相似文献
