摘要
介绍一座沿河道行进方向修建的拼宽桥,在保持路桥同高的条件下,为了降低梁体对河道行洪的影响,解决支座侵水等问题,设计了一种新型的板柱固接体系桥梁。其构造简单,梁高低,阻水面积小,景观效果较好。通过对结构构造进行介绍,对受力特性进行分析,对施工方案进行比选,可为类似设计条件下的项目提供参考。
A widened bridge built along river is introduced. Under the condition of ensuring the same height of road and bridge, in order to reduce the influence of beam on flood discharging of river and to solve the problems of supports inundated in water, a new plate-column solid joint system bridge is designed. Its structure is simple, its beam height is low, its area of water resistance is small and its landscape effect is good. The structure construction is introduced. The stress characteristics are analyzed.The construction schemes are compared and selected. The reference can be provided for the projects under the similar design conditions.
