以某部分斜拉桥为工程背景,采用有限元计算软件ANSYS建立全桥有限元模型,在此基础上对该桥动力特性进行了计算和分析,计算结果表明:考虑桩—土相互作用后明显的使该桥梁的整体刚度降低,故不能忽略桩—土相互作用的影响,可为该桥后续的抗震分析提供依据,同时也为同类桥型的设计和施工计算提供参考。
Taking a part of cable-stayed bridge as the engineering background, the finite element model of the full-bridge is established by using the finite element software ANSYS. Based on the calculation, the dynamic characteristics of the bridge are calculated and analyzed. The calculation results show that considering the obvious interaction between pile and soil So that the overall rigidity of the bridge is reduced. Therefore, the influence of the pile-soil interaction can not be neglected, which can provide the basis for the subsequent seismic analysis of the bridge. It also provides a reference for the design and construction calculation of similar bridges.
