摘要
土石坝加高是目前提升防洪标准、增加库容、解决病害、充分开发利用水资源的较为经济合理的方法。目前国内外对土石坝的加高方式和加高技术研究还不成体系,特别是针对不同加高方式下的新旧坝体结合面的处理、新旧防渗体搭接等问题研究较少。本文结合国内外典型案例,从环境影响、社会经济效益等方面对土石坝加高方式进行分类总结,分析讨论了土石坝加高技术难题与解决方案,可为今后土石坝工程加高设计与施工提供参考。
The heightening of earth-rock dam is an economical and reasonable way to improve flood control standard,increase storage capacity,solve diseases and fully exploit and utilize water resources.At present,the research on heightening methods and heightening techniques of earth-rock dams at home and abroad is not systematic,especially on the treatment of the joint surface of the old and new dam bodies under different heightening methods,the overlapping of the new and old impermeable bodies and so on.Based on typical cases at home and abroad,this paper classifies and summarizes the heightening methods of earth-rock dam from the aspects of environmental impact and social and economic benefits,analyzes and discusses the technical problems and solutions of earth-rock dam heightening,and provides references for the design and construction of earth-rock dam engineering heightening in the future.
