Abstract: In recent years, China's water conservancy and hydropower industry has made great progress, corresponding to the construction of the quality level also put forward higher requirements. In the process of construction and development of water conservancy and hydropower projects, earth-rockfill dam construction technology is a more common and commonly used technology, it has obvious characteristics, not only can significantly improve the efficiency of engineering construction, but also help to reduce the cost of construction. It can guarantee the good quality of the final construction. In this paper, the advantages and disadvantages of earth-rockfill dam construction technology are analyzed, and then the requirements of earth-rockfill dam construction technology in water conservancy and hydropower projects are discussed in detail, in order to provide reference for the future development of this field.
Keywords: water conservancy and hydropower project; earth-rock dam; construction technology
在水電工程的发展历史当中,土石坝施工技术具有着长久的发展历程。跟随着科学技术的全面进步,土石坝以其独特的施工技术优势,在我国的坝工建筑领域,一直处于领先的地位。近年来,随着坝工施工的进程加快,土石坝施工技术被广泛地应用于低坝和高坝的建设当中。它在投入和使用的过程中,表现出了良好的经济价值,因此,被使用的频率也越来越高。在发展的历程中,施工技术取得了巨大的进步,相应而来的是促进了机械设备的改进和建筑材料的日益完善。
土石坝在施工过程中,所使用的材料为就地取材,均为开挖出来的各种石料、土料以及混合材料。而土石坝的具体作业,就是把开挖出来的材料,首先进行抛填,再通过机械碾压的形式,堆砌成挡水坝。根据堆筑材料的不同,可以将坝体分为三类,即以砂砾和土为原材料的土坝;……
