开建一年多来 黄河古贤水利枢纽工程建设驶入快车道 攻坚峡谷间 筑坝守安澜（产经观察·收官之际看工程）

Core Viewpoint - The Huanghe Guxian Water Conservancy Hub Project is a significant infrastructure initiative under China's 14th Five-Year Plan, aimed at optimizing water resource allocation and supporting ecological protection and high-quality development in the Yellow River basin [1][2]. Group 1: Project Overview - The Guxian Project is located between Jixian in Shanxi and Yichuan in Shaanxi, controlling 73% of the Yellow River's water, 60% of its sediment, and 80% of its coarse sediment [2]. - The project is set to enter its construction phase in July 2024, with significant progress already made in the excavation of diversion tunnels [1][3]. Group 2: Construction Challenges - The project faces geological challenges, including varying rock types and stability issues, requiring advanced construction techniques [4][11]. - The diversion tunnels, each over 1 kilometer long with a span of 18.2 meters, demand high precision in construction, with a deviation of only 9 millimeters achieved in the first tunnel [6][4]. Group 3: Technological Integration - The project employs advanced technologies such as 3D modeling and geological radar for pre-excavation analysis, enhancing safety and efficiency [5][9]. - A digital twin of the project is being developed, integrating real-time data monitoring and predictive analytics to improve construction management [7][10]. Group 4: Environmental and Economic Impact - The Guxian Project will significantly improve water supply conditions for 23 counties and 27 industrial parks, benefiting approximately 6.85 million acres of farmland [13]. - The project is expected to generate an average annual power output of about 6.348 billion kilowatt-hours, contributing to regional ecological improvement [13]. Group 5: Construction Scale and Innovation - The dam will be the highest roller-compacted concrete gravity dam in China, with a height of 219.5 meters and a concrete volume exceeding 18 million cubic meters [11][12]. - Innovative transportation solutions, including a large-scale belt conveyor system, are being implemented to manage the logistics of concrete and aggregate delivery [12].
