在实际工作中,我们将《铁路曲线测设用表》(1976年版,以下简称曲线表)介绍的偏角乘率法公式移植应用于曲线桥梁平面布置偏角的计算,其范围根据桥梁设计的实际应用,本文予以增减,见表1。应用该法可将计算点位于任何情况下的偏角均转化为两个角之和,即θ′=δ_1+δ_2(图1);所求的两个角度,实际 In practical work, we apply the formula of angular rate multiplier introduced in “Table of Railway Curve Surveying and Mapping” (1976 version, hereinafter referred to as curve table) for the calculation of the declination of the plane layout of curved bridges. The range of the formula is based on the design of the bridge Practical application, this article be changed, see Table 1. This method can be used to calculate the point in any case the declination are converted into the sum of two angles, that is θ ’= δ_1 + δ_2 (Figure 1); the two angles sought, the actual
