摘要
为了了解施工偏差对斜腿刚构桥受力状况的影响,利用ANSYS通用有限元分析程序,对洛阳市环城高速公路K26+40分离立交桥,进行了三维实体有限元分析。重点考察了斜腿与主梁刚结部位的应力状态。本文分析结果对同类桥梁的施工,具有一定参考价值。
For researching the affection on the internal forces of a prestressed-concret slant-legged rigid frame bridge because of construction deviation , by using the solid element of ANSYS program , a stress analysis for a model of the bridge was conducted . The iso- stress traces of the various parts of the model were plotted , some problems that cannot be found in the routine analysis for internal forces are revealed .
