摘要
为确定高拱坝可利用岩体及其标准,以拉西瓦水电站双曲薄拱坝为例,考虑到建基岩体的自身稳定和上部结构的安全,从岩石强度和岩体承载条件、建基岩体的变形模量条件、岩体风化及坝顶以上高边坡条件、岸坡应力环境条件等4个方面,分析了高拱坝可利用岩体及标准.
About studying the rock foundation and determining the evaluation standard of high arch dam, this article takes hyperbolic thin arch dam of Laxiwa Hydroelectric Power station as an example. It mainly considers the rock foundation stability and the superstructure safety. This article studies and determines the evaluation standard the rock foundation of high arch dam based on four facors, inehluding rock intensity, rock mass load hearing condition, the modulus of deformation, rock mass weathering and high slope, bank slope stress environment, and so on.
