A bearing surface transmits the interaction between an arch dam and its foundation, the strength of which directly affects the constraint of the bedrock to the dam, and thus affects the stress and deformation of the dam. the influence is studied in this paper with nonlinear finite element method, as an example, for a high arch dam in design. the results show that the influence on stress is only limited within the local area near the bearing surface, larger on the maximum principal tensile stress than on the principal compression stress, and the decrease of the strength does not cause unlimited increase of the maximum stress. the influence on the displacement of the top of the dam is smaller than that of the bottom of the dam, especially the relative downstream displacement. at the lower strength of the bearing surface, the relative downstream displacement at the bottom of the dam increases with the decrease of the strength
建基面是傳遞拱壩和基巖相互作用的紐帶，它的強度直接影響基巖對壩體的約束，從而影響壩體的應力和變形.採用非線性有限單元法，以設計中的某高拱壩為例，分析建基面強度對壩體應力和變形的影響.結果表明建基面強度對壩體應力的影響僅限於建基面附近的局部范圍，對最大主拉應力的影響要大於對最大主壓應力的影響，建基面強度的降低不會無限地增大壩體的應力數值；建基面強度對壩頂位移的影響較小，但對壩底位移（尤其是順河向相對位移）的影響較大，當建基面強度較低時，壩底順河向相對位移隨建基面強度的降低而增大 -
