摘要
研究了橡胶支座上梁体横向稳定性,建立了考虑支座变形梁体横向稳定性的计算公式,并对影响梁体稳定的因素进行了分析,最后通过计算不同跨度标准梁梁体稳定性,对桥梁铺架施工中梁体横向稳定性的控制提出了合理的建议,并提出了橡胶支座上梁体稳定性的施工安全标准。
In this paper, the transversal stability of concrete beam on rubber bearings is studied; the calculation method about transversal stability is established; and the influence of some factors on the beam is analyzed. Based on calculations of the transversal stability of beams of different spans, some advices on transversal stability control and safety criteria for bridge construction are proposed.
