【摘要】：在橋梁水平位移監(jiān)測中,基于當前高鐵橋梁不規(guī)則線型增多的情況,針對傳統(tǒng)精度分析方法只能掌握監(jiān)測點沿橋梁中軸線垂直方向的偏差且是基于簡易誤差傳播理論,而施工監(jiān)測中需掌握沿某特定方向的精度。因此,結合跨淮河某橋梁,創(chuàng)新采用誤差橢圓理論對小角法、角度交會法、距離交會等監(jiān)測方法進行精度評定,結果認為小角法對于曲線橋梁適用性較差,而后方交會和極坐標組合方法能夠產(chǎn)生較小的誤差橢圓和點位精度,期望結論對相關橋梁工程有所借鑒。
[Abstract]:In the horizontal displacement monitoring of bridges, based on the increase of irregular lines of high-speed railway bridges, the traditional accuracy analysis method can only master the vertical deviation of monitoring points along the central axis of the bridge and is based on the simple error propagation theory, but the accuracy along a specific direction should be mastered in construction monitoring. Therefore, combined with a bridge across the Huaihe River, the error ellipse theory is used to evaluate the accuracy of small angle method, angle intersection method, distance rendezvous and other monitoring methods. The results show that the small angle method has poor applicability to curved bridges, while the rear intersection and polar coordinate combination method can produce less error ellipse and point accuracy. It is expected that the conclusion can be used for reference in related bridge engineering.
