Core Viewpoint - The article discusses the ongoing large-scale rock hazard management project at the "Diao Zui" rock site in Chongqing, which poses a significant threat to the safety of the Yangtze River's shipping route and the surrounding areas, emphasizing the urgency of the project due to potential economic losses and safety risks [1][2]. Group 1: Rock Hazard Overview - The "Diao Zui" rock site contains approximately 1.406 million cubic meters of hazardous rock, which, if collapsed, could directly threaten the safety of the shipping route, nearby docks, and the lives of over 3,000 people [1][2]. - The rock formation consists of 27 individual hazardous rock units, 50 fractured zones, and 17 isolated stones, with five large slab-like rock bodies that collectively have a volume comparable to dozens of standard football fields stacked 100 meters high [2]. Group 2: Project Implementation - Since 2022, emergency monitoring has been initiated in Fengjie County, with 40 automated devices installed to monitor cracks and stress changes in real-time [2]. - The project employs a comprehensive management plan that includes removal, support, anchoring, and ecological restoration, utilizing advanced techniques such as a 165-meter high suspended scaffold and a material aerial corridor for precise material delivery [4]. Group 3: Economic and Social Impact - The project has an investment of 44.73 million yuan, but it is expected to prevent direct economic losses exceeding 300 million yuan, highlighting the project's importance in maintaining the safety and continuity of the Yangtze River as a vital shipping route [5]. - The successful management of the rock hazard is crucial for protecting the tourism industry, particularly for the Bai Di City and Qutang Gorge, which attract millions of visitors annually [5].
