Cable bent tower anchoring area design method based on steel anchor box
The invention relates to a cable bent tower anchoring area design method based on a steel anchor box. The method comprises the steps that the outline of the steel anchor box is determined; compressed concrete contours located on the two sides of the steel anchor box are determined according to the concrete compression area, and the two compressed concrete contours are not connected; determining the size of the contact part between the contour of the compressed concrete and the contour of the steel anchor box according to the cable force of the stay cable; judging whether the steel anchor box is built in; if the steel anchor box is internally arranged, a constructional concrete contour connecting the two compressed concrete contours is determined, and the constructional concrete contour and the compressed concrete contours jointly form a concrete contour of a cable bent tower anchoring area; if the steel anchor box is externally arranged, the compression concrete outline serves as the concrete outline of the cable bent tower anchoring area, and the space of the steel anchor box is determined. According to the cable bent tower anchoring area design method based on the steel anchor box, the stress behavior is simplified, the tension characteristic of the steel anchor box and the compression characteristic of concrete are fully played, the problem that the concrete cracks due to tension is solved, and the situation that prestressed tendons are arranged in the cable bent tower anchoring area is avoided.
本申请涉及一种基于钢锚箱的索塔锚固区设计方法，其包括：确定钢锚箱轮廓；根据混凝土受压面积确定位于钢锚箱两侧的受压混凝土轮廓，且两个受压混凝土轮廓互不连接；根据斜拉索索力确定受压混凝土轮廓与钢锚箱轮廓之间接触部分的尺寸；判断钢锚箱是否内置；若钢锚箱内置，确定连接两个受压混凝土轮廓的构造混凝土轮廓，构造混凝土轮廓与受压混凝土轮廓共同形成索塔锚固区的混凝土轮廓；若钢锚箱外置，受压混凝土轮廓作为索塔锚固区的混凝土轮廓，确定钢锚箱的空间。本发明提供一种基于钢锚箱的索塔锚固区设计方法，简化受力行为，充分发挥钢锚箱的受拉特性和混凝土的受压特性，解决了混凝土受拉而开裂的问题，避免了索塔锚固区布置预应力筋。
