| 摘 要： | 为了实现黄河流域多沙粗沙区骨干淤地坝坝面低成本过水,分析了淤地坝坝面过水材料的物理力学性能和抗冲性能,并对试验材料的物理力学性能和抗冲性能进行了室内模型试验。结果表明:石灰土、三合土不适合做坝面过水材料;水泥含量为10%的水泥土的抗冻融、抗渗透和抗冲刷等性能均满足10 m以下坝高的坝面过水材料性能要求。采用分段铺设不同材料的方法,可实现坝高高于10 m大型淤地坝的坝面过水要求。

| Abstract: | In order to reduce the cost of materials used in overflow dam face of warping dam in the more sediment and coarse sediment region,it analyzed the anti-erosion performance and mechanical properties of dam face material through experiment and model test,the results show that lime soil and Tabia are not fit for the overflow dam face material.The 10 percents of soil-cement has freeze-thaw osmosis and anti-erosion performance which are fitted for the dam whose height is no more than 10 meters,the method which laying the different materials on different segments of overflow dam face can be filled with the warping dam which is higher than 10m. |
