摘要
淤泥大坝是一种常见的坝型,因其建造材料的特殊性,导致防渗水效果较差.为了提升大坝防渗效果,针对两种加固方案进行探讨.结果显示,方案A中的A13 方案加固后的坝体单宽渗流量相较于初始值减少91.67%;出口渗透比降与初始值相比,减少 93.59%;A13方案改进后坝体的水流浸润线相较于原始高度,减少 40.0%.因此,采用A方案中的A13 方案,坝体满足渗透稳定要求.研究结果对淤泥大坝的防渗技术研究有一定的参考作用.
Abstract
Muddy dams are a common type of dam,and due to the special nature of their construction materials,their anti-seepage effect is poor.In order to improve the anti-seepage effect of the dam,this study explored two reinforcement schemes.The results show that the single width seepage flow of the dam body after reinforcement with A13 scheme in scheme A decreased by 91.67%compared to the initial value.Compared with the initial value,the decrease in export penetration ratio decreased by 93.59%.Moreover,the improved A13 scheme reduces the water infiltration line of the dam body by 40.0%compared to the original height.Therefore,the A13 scheme in scheme A is adopted to ensure that the dam body meets the requirements for seepage stability.This study has a certain reference value for the study of anti-seepage technology of silt dams.
