在曲线计算整正中,不能忽视曲线首尾方向。曲线首尾方向不良,即有反弯或者鹅头,在测量时应在钢轨的外侧量取正矢的负值,然后把负值带进计算表小进行计算。 在测量曲线正矢时,一般只测量曲线正矢的正值,不测曲线正矢的负值,这种方法只适用于曲线正矢状态较好,曲线头尾方向正常,没有反弯或者鹅头时的情况。如果曲线头尾方向不良,有反弯或鹅头时,拨正曲
In the middle of the curve calculation, you can not ignore the direction of the curve. Curvilinear end of the curve is not good, that is, anti-bending or goose head, measuring the outer side of the rail should measure the positive vector negative, then the negative value into the calculation table small calculation. When measuring the positive curve of the curve, it is generally only to measure the positive value of the positive curve of the curve, and the negative value of the positive curve of the curve is not measured. This method is only applicable to the positive curve of the curve, the normal direction of the curve, When the situation. If the curve head and tail direction is not good, there are anti-bending or goose head, dial the positive song
