结合大连红星海世界观项目二号景观桥——不对称独塔双索面斜拉桥,介绍了该斜拉桥钢混组合索塔钢锚箱新颖的构造方式以及受力特点,并采用空间有限元方法对其钢锚箱节段模型进行仿真计算分析,并论述如何选择ANSYS中恰当的Shell单元对薄板进行模拟,并指出了索塔锚固区的应力分布特点。
Combining with the Second Bridge of landscapes - asymmetric single-tower double-cable-stayed cable-stayed bridge in Dalian Hongxinghai Worldview Project, this paper introduced the novel structure and the characteristics of the steel anchor box of steel-concrete composite cable tower of this cable-stayed bridge, The finite element method is used to simulate and analyze the steel anchor box segment model. The paper also discusses how to choose the appropriate Shell element in ANSYS to simulate the thin plate, and points out the stress distribution characteristics of the pylon anchorage zone.
