以下为句子列表：
英文: 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 pape
中文: 建基面是传递拱坝和基岩相互作用的纽带，它的强度直接影响基岩对坝体的约束，从而影响坝体的应力和变形.采用非线性有限单元法，以设计中的某高拱坝为例，分析建基面强度对坝体应力和变形的影响.结果表明建基面强度对坝体应力的影响仅限于建基面附近的局部范围，对最大主拉应力的影响要大于对最大主压应力的影响，建基面强度的降低不会无限地增大坝体的应力数值；建基面强度对坝顶位移的影响较小，但对坝底位移(尤其是顺河向相对位移)的影响较大，当建基面强度较低时，坝底顺河向相对位移随建基面强度的降低而增大.
