| 中文摘要: |
| 胶结颗粒料坝的概念于2009年提出并于2012年在国际发表,我国胶结颗粒料坝行业技术标准于2014年得到批准。本文综述了胶结颗粒料坝的研究进展,重点以胶凝砂砾石坝为例,阐述了断面设计、材料配比和性能试验方法和施工质量控制方面的理念和进展,给出了胶凝砂砾石和胶凝人工砂石的强度、渗透性、抗冻性和绝热温升等试验结果和工程应用实例,归纳总结了胶结颗粒料坝的筑坝基本原则。已建工程实践表明,胶结颗粒料坝具有安全、经济、环境友好等优点,从工程实践看,可以节约投资10%~20%,安全性高、漫顶不溃,并可缩短建设周期,有利于环境保护和水土保持,具备一定的适应性和优越性,为面广量大的中小型水库大坝工程建设提供了新的坝型选择。 |
| 英文摘要: |
| The concept of Cemented Material Dam (CMD) was proposed in 2009 and published in 2012. Chinese Technical guideline of CMD was issued in 2014. Take Cemented Sand, Gravel and Rock (CSGR) Dam as an example, studies on method of dam cross section design, material selection and mix ratio de-sign, and quality control are introduced to explain the concept and principles of CMD. Lab test results on strength, impermeability, freeze thaw resistance and projects application of CSGR are introduced. Based on studies and practices, main principles of CMD were summarized. The applications indicated that the CMD could reduce construction cost by 10%~20% and had higher safety to resist overtopping failure compared with embankment dam. It also has advantages of quick construction and environmental-friendly. CMD pro-vides a new solution for small dam construction. |
