摘要
以宜宾金沙江戎州大桥施工阶段稳定性为分析对象,应用ANSYS程序对各施工阶段稳定性进行了评估,研究了横向风力对中承式钢管混凝土桁拱稳定性的影响,讨论了影响稳定安全系数的各种因素,并提出了管内混凝土的合理加载程序。
In this paper, the construction stability of Rongzhou Bridge across Jinshajiang River in Yibin is analyzed. The ANSYS program is used to evaluate the structural stability of the Bridge at each construction stage. The influences of horizontal wind force on the stability of the half-through concrete-filled steel tube bridge with trussed arch are studied. Eventually, various factors affecting the stability safety coefficients are discussed, and the reasonable loading procedures of concrete in the tubes are suggested.
