As a large span steel arch bridge and located in the west plateau, it is necessary to calculate its dynamical action because it belongs to higher anti - seismic lever
對于柳梧大橋這樣的大跨度鋼拱橋，由於其處于西部高原地區，屬于抗震等級要求較高的橋梁，有必要進行動力計算。 -
The shape optimization design model for an arch dam under the action of static loads is dissolved by using the evolution strategy
摘要採用進化策略求解靜力荷載作用下拱壩體型優化設計的數學模型。 -
The conclusions are list as follows : ( 1 ) the mechanical properties of different parts of the bridge are as follows : arch is under the combined action of compression and bend ; open spandrel beam is under the combined action of tension and bend ; close spandrel beam is under the combined action of compression ( or tension ) and bend, but the axis force is small
本文得出的結論如下： （ 1 ）空腹式剛架拱橋的受力兼具梁和拱的特點。結構各部位的受力特性如下：斜腿為壓彎作用；空腹段梁體為拉彎作用；中跨實腹段梁體為壓彎作用或拉彎作用，但軸向力較小，受力更接近純彎構件。 -
In this paper, using large - scale current finite element software, analysising nanbu jialingjiang bridge as engineering example, considering the united action of arcade and of arch with the structure on crown, the author build several 3d finite element models including original bridge, dangerous bridge, all phases of strengthening bridges and strengthened bridge. in order to decide the most unfavorable load case accurately and quickly, using static analysis method this paper draws out the influence surface of bend moment for main section ; base on built models the paper analyzes the internal forces on entirely strengthening process and knows the damaged degree of dangerous bridge and does feasibility studying on its strengthening method ; finally, the paper simply analyzes the unite action of arcade and of arch with the structure on crown
