Spatial self-anchored suspension bridge reference strand erection error correction method
The invention provides a spatial self-anchored suspension bridge reference strand erection error correction method which comprises the following steps: after a reference strand is erected, calculating a difference value between the reference strand and a design value; according to the tower height of the bridge tower and the deviation of the span of the main beam, the correction amount # imgabs0 # of the reference strand height loss is calculated; temperature sensors are arranged on the reference strand and the main beam, and the reference strand height loss correction # imgabs1 # caused by temperature changes is calculated; calculating the corrected height loss of the reference strand according to the theoretical height loss # imgabs2 # of the reference strand and the height loss correction # imgabs3 # of the three parts, arranging a plurality of temporary slings between the main tower and the splay saddle, pulling the reference strand to move transversely, and pulling the reference strand to a transverse height loss design position. The method has the beneficial effects that the standard strand can be accurately erected under the conditions of large temperature difference and deviation of the height of the main tower and the span of the main beam, the unstressed line shape of the standard strand can be accurately controlled by eliminating correction of the height loss of the standard strand due to the fact that the height of the main tower, the span of the main beam and temperature change are eliminated, and the design requirement is met.
本发明提供一种空间自锚式悬索桥基准股架设误差修正方法，包括以下步骤：在基准股架设完毕后，计算其与设计值的差值；根据桥塔塔高及主梁跨径的偏差分别计算出对基准股失高的修正量#imgabs0#；在基准股上及主梁上布设温度传感器，计算温度变化对基准股失高修正量#imgabs1#；根据基准股理论失高#imgabs2#及上述三部分失高修正量#imgabs3#，计算得到基准股修正后的失高，在主塔与散索鞍之间设置多道临时吊索，拉动基准股在横向移动，将基准股拉至横向失高设计位置处。本发明的有益效果在于：本发明实现了在大温差、主塔高度及主梁跨径存在偏差下精确地架设基准股，通过消除主塔高度、主梁跨径及温度变化对基准股的失高的修正，实现了精确控制基准股无应力线形，满足了设计要求。
