【海珠灣隧道建成通車】
11月12日,广州首条超大直径盾构隧道海珠湾隧道正式建成通车。
通車後,廣州中心城區至廣州南站可實現15分鐘互達,對增強廣州南站集疏運能力,進一步釋放其核心門戶樞紐功能,強化廣州國際綜合交通樞紐地位,提高粵港澳大灣區基礎設施「硬聯通」水準具有重要意義。
[Guangzhou's First Ultra-Large Diameter Shield Tunnel, Haizhu Bay Tunnel, Opens to Traffic] On November 12, Guangzhou's first ultra-large diameter shield tunnel, Haizhu Bay Tunnel, officially opened to traffic. The tunnel is 4.35 kilometers long, with six lanes in both directions. The shield tunneling section was constructed using two 15.07-meter ultra-large diameter shield tunneling machines, employing multiple innovative technologies to overcome the complex geological challenges of the Pearl River Delta's soft upper and hard lower red strata. It also successfully tunneled under multiple waterways of the Pearl River system, achieving millimeter-level settlement control—the first and largest-scale ultra-large shield tunnel with millimeter-level pile foundations in China. After its opening, travel time between Guangzhou's central urban area and Guangzhou South Railway Station will be reduced to 15 minutes. This is of great significance for enhancing the transportation capacity of Guangzhou South Railway Station, further releasing its core gateway hub function, strengthening Guangzhou's status as an international comprehensive transportation hub, and improving the "hard connectivity" level of infrastructure in the Guangdong-Hong Kong-Macao Greater Bay Area.
