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The paper introduces large - scale fem software, algor, by which the auther can build model of hanging box of high pile cap, and simulates accurately three loadcases, which include loadcase behind enclosed concrete, loadcase behind empty water in hanging box, and loadcase behind high pile cap construction. the auther calculates tensor and displacement of hanging box weir when loads exert panels, supports, suspenders, top beams, base beams of hanging box weir. at the same time the auther carrys out th e stability analysis, besides, educes calculational and analytical data, which are tally with construction result in the main
