安徽省小型土石坝输水洞主要病害及加固措施

On main unsafe reasons and reinforcementmeasures of drainage culvert for small earth-rock dam in Anhui province

安徽省水库众多,其中土石坝占比90%以上。输水洞的安全性是影响土石坝安危的主要因素之一。选取了安徽省不同区域小型土石坝,在对输水洞病害进行深入调研的基础上,梳理出了安徽省不同区域小型水库输水洞的病害形式,并对近年来该省小型水库除险加固中输水洞常用措施进行分析,旨在为小型水库输水洞除险加固中选取科学合理的加固措施提供帮助。

There are many reservoirs in Anhui province,within which earth-rock dams account for over 90%.The safety of drainage culvert is one of the main factors affecting the safety of earth-rock dam.On the basis of in-depth investigation of drainage culverts’unsafe reasons,this paper selected small earth-rock dam in different areas of Anhui province,sorted out the forms of unsafe reasons in different areas of our province and analysed common measures about reinforcement of drainage culvert,to provide help for select scientific and reasonable reinforcement measures in the reinforcement of drainage culvert in small reservoirs.
