现场铺轨施工在曲线部份,为了保证钢轨接缝达到对接形式,曲线里股须铺设短轨,因此,需要进行曲线短轨布置计算。为便于现场施工,加速铺轨进度,简化计算方法实属必要。本文采用直接查表方法,即可进行铺设曲线短轨。茲将25米长钢轨曲线短轨布置编制方法介绍于下。一、第一緩和曲线及圓曲线部份短轨位置在具体铺设中情况千变万化,其中主要包括两个因素: 1.第一缓和曲线或圓曲线的第一根钢轨,伸入直线部份的长度X_1、或第一缓和曲线部份X_2(图1)。
On-site track laying In the curve part, in order to ensure that the rail joints meet the form of docking, the short-track in the curve should be laid. Therefore, the short-track curve calculation needs to be arranged. In order to facilitate on-site construction, speed up the progress of laying, simplifying the calculation method is necessary. In this paper, a direct look-up table method can be used to lay the curve of short track. It will be 25 meters long rail curve short track layout method introduced below. First, the first easing curve and circular curve part of the short track position in the ever-changing situation in the specific laying, which includes two main factors: 1. The first easing curve or circular curve of the first rail, extending into the straight part of the length X_1, or the first transition curve portion X_2 (FIG. 1).
