| 摘 要： | 通过对拉瓦拱坝近岸坡岩体风化、卸荷、变形特性深入研究，在满足南体应力、变位、的要求下，通过建基面岩体质量对坝体应力变位敏感性分析，用坝基岩体极阴有在把水工设计与地质主送紧密结合起来，在数值计算基础上用模型评判方法进行拱坝建基面优化。从而在拱坝在面优化工作做了一次有益探索。

| Abstract: | Through deeply study on the features of rock weathering process, unloading and deformation in the bank-sideof Laxiwa arch dam, on the basis of the analysis of the sensitivity of the rock quality to the dam stress changes andin accordance with the requirements of stress, displacement and stability of the dam body, the limit deformationmodulus has been adopted to combine the hydraulic design and geological evaluation so that the arch dam foundation excavation surface could be optimized by fuzzy evaluation based on numerical calculation. |
