Curve incremental launching construction design method for bridge beam pieces
The invention discloses a curve incremental launching construction design method for a bridge beam piece, and relates to the field of bridge construction. The curve incremental launching construction design method for the bridge beam piece comprises the following steps that when it is determined that the beam piece rotates by an angle a from an initial position to an end position around a center O, the front end center and the rear end center of the beam piece move to a point C and a point B from a point A and a point C respectively; the moving directions of the front end center and the rear end center of the beam piece are parallel to the connecting line of the point A and the point C and the connecting line of the point C and the point B. The moving speed of the centers of the two ends of the beam piece in the moving process of the beam piece is calculated according to a speed formula. According to the curve incremental launching construction design method for the bridge beam piece, constructors can conveniently conduct incremental launching construction on the bridge beam piece in place in one step along the curve, so that the operation efficiency is improved, and the requirements of operators are reduced.
一种桥梁梁片的曲线顶推施工设计方法，涉及桥梁施工领域。桥梁梁片的曲线顶推施工设计方法包括以下步骤，确定梁片绕中心O从初始位置旋转角度a移动至终末位置时，梁片的前端中心和后端中心分别从A点和C点分别移动至C点和B点；按速度公式计算梁片移动过程中梁片两端中心的移动速度：梁片的前端中心和后端中心的移动方向分别平行于A点和C点的连线和C点和B点的连线。本申请提供的桥梁梁片的曲线顶推施工设计方法能够方便施工人员将桥梁梁片沿曲线一步顶推施工到位，从而提高了作业效率、减少了作业人员需求。
