摘要
文章以毕节市倒天河综合治理三期工程一号路大桥为依托,采用有限元软件MIDAS-FEA建立拱脚的局部有限元模型,并进行数值模拟分析。通过模拟拱脚在设计荷载下的受力情况,研究钢管混凝土系杆拱桥拱脚应力状态,提出改善拱脚应力状态的措施,为同类桥梁的设计和施工提供依据。
Based on the Road No. 1 Bridge at 3rd Comprehensive Management Engineering of Daotian River, Bijie City, the article applied the finite element software of MIDAS-FEA to establish the local finite element model of arch spring, and conducted the numerical simulation analysis. Through simulating the stress condition of arch spring under the designed load, we studied the arch spring stress state of concrete-filled steel tube tied arch bridge, and proposed some measures to improve the arch spring stress state, providing the basis for the design and construction of similar bridges.
