Beam-arch combined rigid frame bridge and construction method of piers thereof
The invention belongs to the technical field of bridge construction, and particularly relates to a beam-arch combined rigid frame bridge. The rigid frame bridge comprises pile foundations; a bearing platform which is poured on the pile foundation; bridge piers which are arranged corresponding to the bearing platforms, the multiple bridge piers are arranged in the bridge direction at intervals, andthe bridge piers are arranged on the corresponding bearing platforms; a beam body which is supported by a plurality of bridge piers; lower chord supporting beams, one ends of which are connected to the bridge piers, the other ends are connected to the bottom of the beam body, the lower chord supporting beams are located between every two adjacent bridge piers, and the bottom edge lines of the lower chord supporting beams change according to a 2.2-time parabola rule. The combined structure system is clear in structural stress and attractive and novel in appearance.
本发明属于桥梁施工技术领域，尤其涉及一种梁拱组合刚构桥。该刚构桥包括：桩基础；承台，承台浇筑于桩基础上；桥墩，桥墩和承台对应设置，桥墩沿顺桥向间隔布置有多个，桥墩设置在对应的承台上；梁体，梁体通过多个桥墩支撑；下弦支撑梁，下弦支撑梁的一端连接在桥墩上，下弦支撑梁的另一端连接在梁体的底部，下弦支撑梁位于两个相邻的桥墩之间，下弦支撑梁的底缘线按2.2次抛物线规律变化。本发明是一种结构受力明确、外形美观、新颖的组合结构体系。
