龙江水电站枢纽工程主要技术问题研究与工程措施

Key technologies and structural measures for Longjiang Hydropower Station

龙江水电站枢纽工程处于高震区,坝址区地质条件复杂,工程技术难度很高。围绕建设期工程主要技术问题,相继开展了一系列专题研究和科研试验工作,提出工程处理措施和方案,成功解决了拱坝基础地质问题、抗震问题、坝体混凝土温控问题、火山灰掺和料应用问题及引水压力钢岔管优化问题等关键技术问题,成效理想,为工程建设提供了坚实的技术支撑,也积累了宝贵经验。

Longjiang Hydropower Station is located in earthquake-prone area, with complicated geological condition at the dam site that caused great difficulties for technology application. A series of special subject studies and scientific experiments have been conducted in order to overcome key technical obstacles. Solutions have been proposed regarding to geology of arch dam foundation, anti-earthquake, temperature control of dam body concrete, application of volcanic ash admixture and optimization of steel bifurcated pipe. The results are satisfactory that provide solid technical foundation for the project with accumulation of valuable experiences.
