摘要
本文以新疆北部地区某水利工程为研究对象,对土石坝混凝土护坡进行计算比较分析,采用碾压式土石坝设计规范与土坝设计规范分别计算混凝土护坡厚度,结果显示:当坝面坡度系数m=2—5时不同混凝土护坡计算方式其结果差异较明显,通过稳定分析等算法最终确定合理混凝土护坡厚度0.25m较合适。
This paper, taking a water project in northern Xinjiang region as an example, carried on the comparative analysis for the calculation of concrete slope protection thickness of earth-rock dam, with design specification of roller compacted earth-rock dam and design code of earth dam. The results shows the difference is more obvious when dam slope coefficient m - 2-5 under different concrete slope calculation. The reasonable and appropriate thickness of 0.25m of concrete slope protection is determined by the final stabilizing analysis and algorithms.
