强震区砂砾石筑坝技术进展

Dam construction technology of using sand gravel in earthquake zone

现代工程技术的长足发展,让我国西部强震区建设高混凝土面板和沥青心墙砂砾石坝成为可能。在分析国内外砂砾石坝的基础上,对砂砾石筑坝的工程特性、填筑标准与材料分区进行了研究,提出了解决其抗震稳定性的措施,包括合理的坝体材料分区设计、加强坝体抗震措施和施工技术进步等。

Abstract： Along with development of modern engineering technologies, it is possible to construct high concrete faced rockfill dam and sand-gravel asphaltic corewall dam in earthquake zones in the western part of China. Based on analysis of sand gravel dam built home and abroad, studies on engineering features of sand gravel dam, filling standard and material zoning are carried out. Measures for consolidating its stability in earthquake prevention are proposed, including design of material zoning of dam bodies and measures for earthquake prevention and construction technologies.
