Suspension bridge gravity type anchorage and construction method thereof
The invention relates to the technical field of bridges, in particular to a suspension bridge gravity type anchorage and a construction method thereof. The anchorage structure comprises a foundation, the foundation comprises side faces, a bottom face and a top face, the side faces are obliquely arranged towards the bottom face from top to bottom, and the size of the top face is larger than that of the bottom face; and the section width of the side face in the transverse bridge direction is gradually narrowed towards the side where a main cable is located from back to front in the longitudinal bridge direction. The gravity type anchorage of the suspension bridge is excellent in stress performance and high in anti-sliding and anti-overturning capacity, the requirement for the bearing capacity of a base is low, different inclination angles can be adopted in all directions of the side face of the base so as to adapt to different terrain and geological conditions around the anchorage, and environmental adaptability is high. In addition, due to the structural characteristics of the anchorage foundation, the earthwork excavation amount is small, the concrete pouring amount is small, the influence on the environment is small, the cost is reduced, the excavation gradient of a foundation pit is kept consistent with the inclination degree of the foundation during construction, formwork erecting and backfilling procedures are not needed, and the construction period is short.
本发明涉及桥梁技术领域，具体涉及一种悬索桥重力式锚碇及其施工方法，其中锚碇结构包括基础，基础包括侧面、底面和顶面，侧面从上而下朝向底面倾斜设置，顶面比底面尺寸大；侧面沿横桥向的截面宽度沿纵桥向方向从后往前朝向主缆索所在侧逐渐收窄。本发明所提供的悬索桥重力式锚碇，不仅受力性能优异，抗滑移和抗倾覆能力强，而且对基底承载能力要求低，可通过在基础侧面各方向采用不同的倾角以适应锚碇四周不同的地形、地质情况，环境适应性强；此外，由于锚碇基础本身结构特点，开挖土方量少、混凝土浇筑量小，对环境影响小，也降低了成本，而且在施工时基坑的开挖坡度在施工时与基础倾斜程度保持一致，不需要立模和回填工序，施工周期短。
