Linear adjustment calculation method of bridge arch ring and bridge arch ring construction method
The invention provides a linear adjustment calculation method for a bridge arch ring, and the method is used for calculating an opening angle between a first segment and a second segment based on the actual position of the installed first segment and the target positions of all segments, so that the actual positions of all segments are within a preset allowable value of the target position of each segment. Comprising the following steps: S1, acquiring the actual elevation of an installed first section, and calculating the elevation deviation of the first section; s2, calculating the elevation deviation of the ith section from the second section to the Nth section; s3, setting a preset opening angle, and determining an elevation correction value of the ith section based on the preset opening angle, the arch ring height and the target position of the ith section; s4, determining an elevation residual error value of the i-th section, and judging whether the elevation residual error value of the i-th section is smaller than or equal to a preset allowable value or not; and S5, when necessary, adjusting the opening angle so as to enable the elevation residual error values from the second section to the Nth section to be smaller than or equal to the preset allowable value.
本发明提供了一种桥梁拱圈的线形调整计算方法，用于基于已安装第一节段的实际位置和所有节段的目标位置来计算第一节段和第二节段之间的张口角度，以使得所有节段的实际位置均在每个节段的目标位置的预设容许值内，包括：S1、获取已安装第一节段的实际高程，并计算第一节段的高程偏差；S2、计算第二节段至第N节段中的第i节段的高程偏差；S3、设置预设的张口角度，并基于所述预设的张口角度、拱圈高度和第i节段的目标位置来确定第i节段的高程改正值；S4、确定第i节段的高程余差值，并判断第i节段的高程余差值是否小于或等于预设容许值；S5、当需要时调整所述张口角度以使得第二节段至第N节段的高程余差值均小于或等于所述预设容许值。
