The Qingyang Tunnel is located at the junction of Zhangqiu District in Jinan and Zouping County in Binzhou, with a total length of 10.1 kilometers. It is a single-tube, double-track high-speed railway tunnel constructed by China Railway Tunnel Group. Construction began in August 2015. Part of the tunnel passes through shallow-buried geology and crosses 2 major fault zones and 12 faults, posing considerable construction safety risks. During project construction, the Jinan-Qingdao High-Speed Railway Company fully implemented standardized management and safety risk management, strengthened inspection and supervision of processes, construction methods, equipment, and work team leaders. The construction unit carried out advanced geological forecasting and strictly implemented measures such as excavation methods, excavation footage, and support construction. Under the premise of ensuring safety and quality, the schedule target was achieved ahead of time. After 639 days and nights of hard work, the tunnel was finally holed through smoothly.

As the first railway in China led by local authorities, the Jinan-Qingdao High-Speed Railway has always aimed at being good, fast, and economical, striving to build a century-long high-speed railway project. In terms of safety and quality, it has fully implemented standardized management and risk management for construction projects, implemented safety and quality management responsibilities for all staff at every level and on-site safeguard measures, and achieved the project quality and construction safety goals. Since the start of construction, the Shanghai Railway Supervision and Administration Bureau of the National Railway Administration has conducted 9 supervisory inspections of the entire Jinan-Qingdao High-Speed Railway line, and no issues were reported on any occasion. The Shanghai Railway Supervision and Administration Bureau spoke highly of the safety and quality management work across the line. In terms of construction progress, it has given full play to the advantages of local controlling stakes, created a favorable external environment, and achieved efficient advancement of project construction. In terms of investment control, it has focused on research in areas such as project bidding, design scheme optimization, material procurement, and financing, saving a large amount of construction funds.
At present, the works below the track of the Jinan-Qingdao High-Speed Railway have been basically completed. Track laying will begin in the Qingzhou section at the end of July this year, and the pre-station works are expected to basically meet completion acceptance conditions by the end of September. Joint commissioning and testing are planned to begin in June 2018, and the line is expected to meet opening conditions by the end of 2018.
