漢江特大橋合龍!國內最大跨度梁桁組合斜拉橋亮相西十高鐵

近日,西安至十堰高速鐵路建設迎來重要里程碑,漢江特大橋順利實現合龍。這座大橋由武九客專湖北公司負責建設管理,鐵一院承擔勘察設計,中鐵十一局負責施工。作為國內最大跨度的梁桁組合結構斜拉橋,漢江特大橋的設計主跨達到了420米。

漢江特大橋坐落于湖北省十堰市鄖陽區,是西十高鐵項目的關鍵控制性工程。大橋全長917.45米,擁有兩座高達186.5米的H形主塔,并設置了80對斜拉索,采用空間雙索面體系以扇形布置,展現出其雄偉壯觀的設計。

據中鐵十一局西十高鐵項目總工程師普銀波介紹,漢江特大橋所采用的梁桁組合結構是一種創新的橋梁設計形式,這在高速鐵路斜拉橋的建設中是首次應用。施工過程中,建設者首先完成了混凝土主梁的建設,隨后在其上安裝了鋼桁梁,這一獨特的施工方式確保了大橋的穩定與安全。

西十高鐵線路自陜西西安起始,向東南方向穿越秦嶺山脈,途經商洛,最終抵達湖北十堰,全長約255.7公里,設計時速高達350公里。這條高鐵線路的建設,將極大地縮短西安與十堰之間的通行時間,預計通車后,兩地之間將實現1小時通達,同時,西安至武漢的行程也將縮短至約2.5小時。

漢江特大橋的順利合龍,標志著西十高鐵建設取得了重大進展,為項目的整體推進奠定了堅實基礎。隨著后續工程的持續進行,西十高鐵有望成為連接陜西與湖北的重要交通紐帶,進一步促進區域間的交流與合作。
