Steep slope abutment structure with temporary anchorage and construction method
The abrupt slope bridge abutment structure comprises a step foundation, a front wall, side walls, an abutment top, anchor cables and inhaul cables, and the bridge abutment foundation is in a step shape and adapts to the steep slope terrain; the abutment body is composed of a front wall and side walls, the front wall is provided with anchor cable holes and inhaul cable holes, anchor cables penetrate through the anchor cable holes in the front wall to penetrate into a rock mass, the anchoring force of the bridge abutment serving as a temporary anchorage is enhanced, inhaul cables are anchored to the front wall in the arch bridge construction process, and the cable force of the inhaul cables is jointly borne by the anchor cables and the bridge abutment. According to the bridge abutment structure, excavation of side slopes is reduced to the maximum extent, the natural environment is protected, the bridge abutment size is reduced, the concrete volume is small, cost is saved, and the construction period is shortened.
本发明公开了一种兼具临时锚碇的陡坡桥台结构，包含台阶基础、前墙、侧墙、台顶、锚索和拉索，所述桥台基础为台阶状，适应陡边坡地形；台身由前墙和侧墙组成，前墙设置锚索孔和拉索孔，锚索穿过前墙锚索孔深入岩体中，加强桥台作为临时锚碇的锚固力，拱桥施工过程中的拉索锚固在前墙上，拉索索力由锚索以及桥台共同承担。该桥台结构最大限度减少了边坡的开挖，保护自然环境，桥台尺寸减小，混凝土方量较少，节约成本，缩短施工工期。
