In the end, the steel - reinforced concrete arched bridge ( chun ' an weiping bridge ), which span is 198m, is analyzed by the proposed three - dimensional nonlinear finite element method and also those gained conclusions are directly adopted in the computation. the universal stability coefficient and nonlinear buckling stability coefficient of the bridge are respectively computed, in which the dead load and the live load are assembled according to the criterion. on the other side, the regularities of creep deformation and subsidiary stress of the investigated bridge under the first - stage dead load are carefully researched
最後，將本文所提出的三維非線性分析方法及其主要研究成果直接應用於198m跨勁型骨架式鋼管混凝土拱橋「淳安威坪大橋」的分析計算中，對該橋在最不利恆載和活載組合下的一般特徵值失穩系數和非線性屈曲系數進行了對比研究，並對一期恆載長期作用下該橋的徐變變形、附加應力以及截面應力、應變重分佈規律分別進行了深入研究。 -
Secondly author calculates and analyses normal stress and shear stress of the girder for a assembling post - tensioned concrete skew girder bridge with a span of 40 m due to the actions of the dead load, temperature changes, shrinkage and creep of concrete and live loads, and calculates and analyses normal stress and shear stress of diaphragms due to the actions of the subordinate phase dead load, temperature changes, shrinkage and creep of concrete and live loads
其次重點對跨徑為40m標準設計的裝配式后張預應力混凝土斜梁橋在恆載、溫度變化、混凝土收縮和徐變、活載作用下主梁的正應力、豎向變形和恆載、活載作用下主梁的剪應力進行計算分析。計算分析橫隔板在二期恆載、溫度變化、混凝土收縮、活載作用下的正應力、剪應力。
