风雪折多山

Core Viewpoint - The construction of the Duzha Mountain Tunnel is a critical project aimed at improving transportation safety and efficiency in the Sichuan-Ganzi region, significantly reducing travel time across the challenging terrain of the Duzha Mountain [4][9]. Group 1: Project Overview - The Duzha Mountain Tunnel is part of the Sichuan-Tibet corridor and is considered a key engineering project, with multiple tunnels being constructed simultaneously in the area [2][4]. - The tunnel construction began in 2018 and is expected to be completed in approximately two years, with current progress at nearly 70% for the National Highway 318 section and about half for the Kangxin Expressway section [9]. - Once completed, the travel time over Duzha Mountain will be reduced from 30 minutes to approximately 8 minutes, enhancing emergency response capabilities and promoting economic development [4][9]. Group 2: Challenges and Conditions - The geological conditions of Duzha Mountain are extremely complex, with the presence of multiple geological fault zones leading to challenges such as mud bursts and water inflow during construction [5][9]. - The harsh weather conditions, including heavy snowfall and low temperatures, complicate the construction process, with workers facing high-altitude sickness and difficult working environments [6][8]. - The construction site has seen over a thousand workers in the past year due to the challenging conditions, with a focus on ensuring timely payment and worker welfare [6][8]. Group 3: Economic and Social Impact - The Duzha Mountain region has seen a significant increase in traffic, with daily vehicle flow rising from approximately 2,000 in 2020 to about 20,000 recently, indicating a growing interest in tourism and economic activity [9][12]. - The local economy is benefiting from the construction projects, with the Ganzi region's GDP per capita increasing from about 15,000 yuan in 2012 to over 50,000 yuan in 2024 [12]. - The development of infrastructure, including the Duzha Mountain Tunnel, is expected to facilitate better access to the region, enhancing the quality of life for residents and promoting tourism [12][13].
