摘　　要：以国外某水电站设计为依托,在国内外不同技术标准下,同时结合工程特点考虑了国外业主及咨询要求,对重力坝抗滑稳定从荷载计算、组合工况、计算采用公式参数以及计算结果等方面进行了比较分析。总体,两者均以应力和稳定性分析作为重力坝坝体断面设计的依据,以材料力学法和刚体极限平衡法作为基本计算方法,所考虑的作用基本一致,但作用组合和一些荷载计算有差别,分别计算的大坝抗滑稳定结果有一定的差异。设计在符合设计标准的同时,也要满足与业主合同要求,综合各方面因素,在保证安全性的前提下进行合理经济的设计,才能更好的"走出去"。Relying on the design of a hydropower station abroad, under different technical standards at home and abroad, taking into account the characteristics of the project and the requirements of foreign owners and consultants, the anti-sliding stability of gravity dam is compared and analyzed in terms of load calculation, combined working conditions, formula parameters and calculation results. Generally speaking, both of them take stress and stability analysis as the basis of cross-section design of gravity dam, and take material mechanics method and rigid body limit equilibrium method as the basic calculation method. The effect considered is basically the same, but the combination of action and some load calculation are different, and the results of antisliding stability calculated by them are different. While meeting the design standards, the design should also meet the requirements of the contract with the owner and integrate various factors. Reasonable and economical design under the premise of ensuring safety can better “go out”.
