摘要
根据重力坝和土石坝剖面设计理论,对超贫胶结材料坝的剖面形式进行研究,通过对不同胶凝材料用量的超贫胶结材料坝进行坝坡稳定分析,拟合得出胶凝材料用量与坝坡稳定坡比值之间的曲线关系,并得出超贫胶结材料坝胶凝材料用量小于40 kg/m^3时,坝体剖面更趋于土石坝剖面,介于40-70 kg/m^3之间时,坝体剖面既有混凝土重力坝的特征又有土石坝的特征,大于70 kg/m^3时,坝体剖面则属于重力坝剖面的结论。
Based on the section design theory of the gravity dam and earth-rock dam, the profile form for the over lean cemented material dam was studied, and the slope stability analysis was performed on the over lean cemented material dam with different dosages of cementing materials. Then the curve for the dosage of cementing material and the stable slope ratio was fitted. It is concluded that the dam section is of the characteristics of the earth-rock dam, both the concrete dam and earth-rock dam, and the gravity dam when the dosage of cementing material is less than 40 kg/m^3, in the range of 40 - 70 kg/m^3, and greater than 70 kg/m^3, respectively.
