摘要
双江口水电站300 m级心墙堆石坝是世界在建的第一高坝,在可研阶段开展了坝基覆盖层及筑坝材料特性、防渗土料改性、坝体结构型式及分区方案、抗震安全评价及抗震措施、智能大坝管控系统等一系列关键技术研究,取得了丰富的研究成果。而随着工程建设的推进和技术的不断发展,还需在河床覆盖层建基条件、坝体结构分区及坝料特性、特高土石坝长期变形特性、高海拔冬季土料冻融规律及大坝防渗土料施工措施、特高坝安全监测等方面的关键技术进行深入研究,以保证工程的科学建设。
The 300 m level core wall rockfill dam in Shuangjiangkou Hydropower Station is the highest dam under construction in the world.In the feasibility study stage of the project,a series of researches have been carried out on the key construction techniques of such ultra-high dam,including the characteristics of the dam foundation overburden layer and dam construction materials,the modification of impervious soil materials,the dam structure type and zoning scheme,the seismic safety evaluation and resistance measures,and the intelligent dam management and control system.With the advancement of the project construction process and the continuous development of the engineering technology,further study on other key techniques is necessary to ensure a scientific construction of the project,including the foundation conditions of the riverbed overburden layer,the structural zoning and material characteristics of the dam,the long-term deformation characteristics of ultra-high embankment dam,the freezing-thawing characteristics of soil materials in winter and high altitude areas,the construction technique of impervious soil materials,and the safety monitoring of ultra-high dam.
