Double asymmetric space steel arch bridge structure
The invention relates to the field of bridge engineering, in particular to a double asymmetric space steel arch bridge structure which comprises a bridge deck system, side steel columns, main arches, inclined struts, half-through arch feet and through arch feet. Bearing platforms for bearing the bridge deck system are arranged at the two ends below the bridge deck system; one end of the bridge deck system is in sliding connection with the corresponding bearing platform through a support; the other end of the bridge deck system is rigidly connected with the corresponding bearing platform through the inclined struts and the side steel columns; the main arch is arc-shaped, one end of the main arch penetrates through the bridge deck system and is arranged on the bearing platform close to the side steel columns, and the other end of the main arch is arranged above the bridge deck system; the through arch springing is arranged on the bridge deck system, and the main arch penetrates through the bridge deck system and is connected with the bridge deck system through a support; the ends, close to the side steel columns, of the main arches are rigidly connected with the bridge deck system through the half-through arch feet and are rigidly connected with the upper portions and the lower portions of the side steel columns through the inclined struts, the water erosion environment is better adapted, the stability of the main arches and the bridge deck system is improved through the wind braces and the suspenders, and the anti-seismic and wind-resistant coefficients are improved.
本发明涉及桥梁工程领域，具体是涉及一种双重非对称空间钢拱桥梁结构，包括桥面系、边钢柱、主拱、斜撑、中承式拱脚和下承式拱脚；桥面系的下方两端设置有用于承载桥面系的承台；桥面系的一端通过支座与对应承台形成滑动连接；桥面系另一端通过斜撑和边钢柱与对应承台形成刚性连接；主拱呈弧形形状，主拱的一端穿过桥面系设置在靠近边钢柱的承台上，主拱另一端设置在桥面系上方；下承式拱脚设置桥面系上，主拱穿过桥面系的位置通过支座与桥面系连接；主拱靠近边钢柱的一端通过中承式拱脚与桥面系刚性连接，通过斜撑与边钢柱上下均为刚接，更加适应水侵蚀环境，并且风撑、吊杆提高主拱与桥面系的稳定性，提高其抗震和抗风系数。
