Hardfill筑坝材料发展的现状和面临的挑战

Status and challenges of Hardfill material

Hardfill材料是继RCC后的一种新筑坝材料,它是将胶凝材料和水添加到河床砂砾石或开挖废弃料等容易在坝址附近获得的岩石基材中,然后用简易的设备进行拌和而得到的一种低强度筑坝材料。Hardfill材料由于具有独特的经济技术优势而逐渐蓬勃发展起来,具有良好的应用前景。但是作为一种新型材料,仍然面临着许多困难和挑战。结合现有研究成果,总结了Hardfill材料的发展现状,分析和讨论了其存在的问题及解决办法,以期为Hardfill材料的进一步发展和推广应用提供有益的参考。

Hardfill material is a new material used in dam construction after RCC.It is a low strength material made by adding cement and water to the rock-based materials such as the riverbed gravel or excavated waste materials that can be obtained easily near the dam sites and then mixed by simple equipment.Owing to its unique advantages both in economy and technology,Hardfill material has been booming and has a good perspective.However, as a new material, it also faces many difficulties and challenges.Combined existing research, this paper summarized the present development situation of Hardfill materials, analyzed and discussed the existing problems and solutions to provide a effective reference for the further development and application of Hardfill material.
