近日,世界最大、最深的全地下高铁站房,也是全球首例单层大跨度网壳穹顶钢结构工程——于家堡高铁站正式竣工。于家堡站是京津城际高铁延伸线的终点站。于家堡站建成后,从北京南站到达于家堡的时间将缩短至45min。施工方中国中铁建工集团在没有现成经验可供借鉴的情况下,克服了基坑深、地质差、地下水多等难题,为国内全地下高铁站房建设填补了空白,并创造了多项“世界之最”。
Recently, the world’s largest and deepest underground high-speed rail station house, is also the world’s first single-story long-span reticulated dome steel structure project - Yu Jiabao High Speed Rail Station was officially completed. Yujiapu station is the terminus of Beijing-Tianjin inter-city high-speed rail extension line. Upon completion of Yujiapu Station, the time from Yuzhengpu to Beijing South Railway Station will be shortened to 45min. Construction side China Railway Construction Corporation in the absence of readily available experience to learn from the case, to overcome the deep foundation pit, poor geological conditions, groundwater and more difficult problems for the domestic underground high-speed rail station building to fill a gap and created a number of “best in the world”.
