铁路桥梁桥位位于緩和曲綫和圓曲綫上时,避車台之設置随曲綫半径不同其布置也就不同。大148避車台标准图,当桥梁位于曲綫上布置方法极为复杂,在計算时較繁瑣,施工亦不方便。笔者認为桥梁位于曲綫上时,完全可以簡化計算,只需改变其中个別杆件(图1,图2中N_1,N_2),其余仍可以采用大148标准图之杆件尺寸。图1表示直綫桥梁上避車台布置簡图,图2表示曲綫桥梁上避車台布置簡图。
When the railway bridge bridge is located on the easing curve and the circular curve, the arrangement of the avoidance car platform varies with the radius of the curve. Large 148 standard car avoidance map, when the bridge is located on the curve layout method is extremely complex, more complicated in the calculation, the construction is not convenient. I believe that the bridge is located on the curve, can simplify the calculation, just change one of the individual rod (Figure 1, Figure 2 N_1, N_2), the rest can still use a large 148 standard rod size. Figure 1 shows the simplified layout of the evacuation platform on the straight-line bridge, and Figure 2 shows the simplified layout of the evacuation platform on the curved bridge.
