中文摘要:
      为给工程规划设计、建设和运行的质量、安全管理提供技术参考,对土质心墙土石坝即心墙坝的沿革及体型和材料发展历程进行了回顾。将国际国内心墙坝发展过程划分为早期发展、现代化过渡、高速发展、发展低潮、发展新高潮等5个阶段,对各阶段国内外心墙坝坝高发展,坝体体型结构变化,筑坝材料选择范围拓展,施工工艺进步等代表性发展进行了分析。心墙坝发展适应了世界经济社会发展要求和开发条件变化过程,前期解决了坝坡稳定和单纯渗流问题,后期持续改进,较好应对了不断出现的变形及相关渗流控制新问题。坝高突破的同时,体型趋向标准、坝料来源逐步拓展。岩土力学理论、施工控制技术的进步,是心墙坝发展的持续推动力量之一。通过持续研究,提升预测分析能力和施工控制水平,心墙坝冲击更大坝高的技术条件将逐渐成熟。
英文摘要:
      In order to provide technical reference for quality and safety management of engineering planning, design, construction and operation, the evolution, configuration and material development of earth core embankment dams (ECEDs) are reviewed. The construction history of ECEDs is summed up as 5 stages, including early development, modernization transition, high speed development, low tide development and new upsurge of development. The representative progresses of each stage are introduced, including increasing of dam height,change in dam body configuration,expansion of dam building material,advance of construction technology, etc. The development of ECEDs adapts to requirements of the world economy and society, as well as the change in development condition. The stability and simple seepage problems were solved in early stage of development. And then,there was a continuous improvement. The emerging deformation problems and related new seepage control problems were dealt with. At the same time of the breakthrough of dam height, the body tended to standard, dam material source gradually expanded. The progress of geotechnical mechanics theory and construction control technology is one of the continuous driving forces for the development of ECEDs. Through continuous research and improvement of prediction and analysis ability, as well as construction control technology, the technical conditions for ECEDs to breakthrough to higher level will gradually mature.
