According to construction features of three - span prestressed concrete and continuous rigid frame box with v pier bridge, the paper demonstrates the shell finite element theories, c onstruct the spatial model, and researches its spatial stress and variable regularity under different loads including uniform load, concentrated load and prestressing force wire. morever, the paper studies vibratory modal of three - span prestressed concrete and continuous rigid frame box with v pier bridge, and sets about experimental investigation of the corresponding practical bridge
本文根據典型的三跨預應力混凝土墩連續剛構橋的特點，提出採用板殼有限元法計算理論，建立其空間分析模型，研究該橋在不同荷載（均布恆載、集中活載、預應力束）支承條件下的空間受力特性和變化規律：探討了典型三跨預應力混凝土墩連續剛構橋的空間靜動力特性及相應的振動模態；探索一般的平面理論預測值與實際空間效應的差異，並進行相應的試驗研究。
