《工务规则》第134条规定。运营中的桥梁,桥上线路中心线与梁跨中线的偏差,钢梁达到50mm,圬工梁达到70mm时……应进行调整。 1979年我们利用增加缓和曲线长度的方法,调整了嫩林线上某一小桥桥上线路中心线与梁跨中线偏差120mm,经过研究,用以下计算方法调整线桥中线偏差较为方便。 一、在圆曲线范围内的计算调整公式导出(图1) Article 134 of the Public Works Regulations states. Operation of the bridge, bridge line center line and the deviation of the beam across the centerline, the steel beam reached 50mm, 圬 beam reached 70mm ... ... should be adjusted. In 1979, we used the method of increasing the length of the easing curve to adjust the deviation of 120mm between the line centerline and the midline of a bridge on a small bridge on the Nei Lin line. After studying, it is more convenient to adjust the center line deviation of the line bridge by the following calculation method. First, calculate the formula within the circle curve derived formula (Figure 1)
