随着高等级公路的发展,铰接斜板桥以它顺从线形跨越的合理性、运输安装方便和施工周期短的特点而广泛用于跨越和立交工程中。一般为了保证斜板的稳定性,铰接斜板桥在各板端的锐、钝角均设置支座。由于铰接斜板既不同于铰接正交板,又不同于整体式斜板,所以各板端锐、钝角支反力分布比较复杂,至今尚未见到有关这方面比较成熟的分析结果。因此,在以往的铰接斜板桥支座设置中,大多数是参考整体式斜板支反力的分布特性,偏保守
With the development of high-grade highways, hinged sloping bridges are widely used in overpass and overpass projects due to their reasonableness of crossing obedient linearity, convenient transportation and installation, and short construction period. In general, in order to ensure the stability of the swash plate, the hinged swash plate bridge is provided with a support at the sharp and obtuse angles of each plate end. Since the hinged swashplate is different from the hinged orthogonal plate and the integral swash plate, the distribution of the sharp and obtuse angles of each plate is rather complicated. So far, no more mature analysis results have been seen in this respect. Therefore, in the past, the hinged slab bridge bearing arrangement, most of the reference is the overall distribution characteristics of the swash plate supportive force, partial conservative
