Group 2: Recovery Efforts - The government aims to restore and rebuild within a framework of "one year for basic recovery, three years for comprehensive enhancement, and long-term high-quality development" [2]. - A total of 424 rural roads were interrupted, with 364 already cleared, and efforts are ongoing to restore all major roads [2]. - The Miyun District has initiated a comprehensive recovery plan, including the establishment of a support mechanism for community involvement [2][7]. Group 3: Characteristics of the Rainfall - The rainfall lasted for seven days, with an average precipitation of 366.6 mm in Miyun, and localized maximum rainfall reaching 573.5 mm [3]. - Extreme weather events included two instances of over 180 mm of rainfall within three hours, which are historically rare and highly destructive [3][4]. Group 4: Emergency Response - The Miyun District's emergency response included the evacuation of 16,000 people from 205 villages and towns [5][6]. - The local government acknowledged shortcomings in their disaster preparedness plans, particularly regarding the senior care center, which was not included in the evacuation plans despite its vulnerability [6]. - Continuous efforts are being made to ensure the safety of residents, including the reinforcement of infrastructure and emergency services [7].

Core Viewpoint - Beijing has set a goal for post-disaster reconstruction, aiming for "basic recovery in one year, comprehensive improvement in three years, and long-term high-quality development" [1] Group 1: Reconstruction Plan - The city will formulate an overall plan for recovery and reconstruction [1] - The plan will be aligned with the "14th Five-Year Plan" and will focus on major projects to achieve recovery and enhancement goals [1] - A mechanism for paired assistance will be established to encourage participation from the entire society [1]

Core Viewpoint - The construction of the National Highway 108 Phase III project in the Mentougou District is a significant infrastructure development aimed at improving regional traffic patterns, enhancing disaster prevention capabilities, and stimulating economic growth in the western part of Beijing [1][8]. Group 1: Project Overview - The National Highway 108 Phase III project spans 3.72 kilometers, starting from the west side of Songshuling and ending at Lujia Tan Village, designed as a first-class highway with a speed limit of 60 km/h and includes a tunnel, three mainline bridges, and eleven culverts [3][8]. - The Songshuling Tunnel, measuring 2.6 kilometers in length and with a maximum depth of 156 meters, employs a "separated double-tunnel" design to navigate complex geological conditions [3][4]. Group 2: Engineering Challenges and Solutions - The project faces high construction risks due to geological complexities, including fault zones and sinkholes, prompting the use of advanced technologies such as geological radar and predictive geological surveys to ensure stability during excavation [3][4]. - Safety measures include precise control of blasting operations, with vibration speeds not exceeding 5 cm per second, and the installation of monitoring points within the existing old tunnel nearby [4]. Group 3: Infrastructure Benefits - The new road will replace the winding mountain road, significantly reducing travel time and improving accessibility between the Mentougou and Fangshan districts [3][8]. - The construction of the Lujia Tan interchange, which connects the new mainline with the old road, is crucial for enhancing connectivity and flood prevention, as the new bridge structure elevates the roadway and incorporates a flood discharge channel [6][8]. Group 4: Strategic Importance - The project is part of the "three horizontal and three vertical" road network in western Beijing, which is essential for disaster recovery and emergency response, as demonstrated during the severe flooding in July 2023 [8][10]. - The National Highway 108 is being prioritized as a key project for post-disaster recovery and reconstruction efforts in Beijing [8][12].
