福建省病险土石坝加固技术研究

Research on rehabilitation technology for earth-rock dams in Fujian province

福建省以防洪、灌溉为主的水库2435座,其中险库458座,病库1003座。在深入研究土石坝渗流病害特点和土石坝渗流控制理论之后,分析、总结国内外主要堤坝防渗加固技术,进行有限元计算分析和防渗墙材料试验研究,针对福建省病险土石坝渗漏及变形情况,提出了适应福建省病险土石坝特点的综合处理技术和加固模式。

There are 2 435 reservoirs mainly for flood prevention and irrigation in Fujian province. Among them, there are 458 dangerous reservoirs and 1 003 diseased reservoirs, This paper, after research on seepage characteristics and seepage control theory of earth-rock dams, analysed and summarized main anti-seepage rehabilitation technology. Furthermore, finite element calculation method and anti-seepage material test were taken. According to seepage and deformation of diseased earth-rock dams in Fujian province, treatment technology and rehabilitation model were advanced in this paper, for reference.
