铁路基础设施的缺口构成瓶颈，限制了整个铁路网的运力。由于它们的设计和几何形状，这些转弯迫使速度限制。由于需要确保适当的投票技术条件，因此正在进行科学研究和使用现代技术解决办法。到目前为止，还没有根据相关几何关系对双滑道岔几何中心的正确位置进行试验。因此，本研究的主要目的是通过测量道岔的水平曲线和几何不规则性来证明双滑移道岔几何中心的位置和圆形改道轨道曲线的几何条件。这种测量方法的应用，参考了在双滑道口和外滑道口的几何依赖而产生的凹道口，定义和实施（也称为检查道口几何中心正确位置的方法-双滑道口和外滑道口几何中心的测量和监测（SMDOST）），通过磁测量广场（MMS）和电子全站仪。该方法还建议测量改道轨道的水平长度。本文介绍了使用SMDOST和MMS方法进行现场测量的结果，这些方法用于对道岔几何条件进行分析和评估，从而展示了导致道岔变形的不规则性。验证了基于MMS和全站仪的SMDOST方法的有效性。所进行的研究的观察结果表明，忽视对投票结果几何形状的测量导致了投票条件的额外不规则性。
The turnouts in railway infrastructure constitute bottlenecks, limiting the capacity of the entire railway network. These turnouts force speed limits due to their design and geometry. The need to ensure the proper technical condition of turnouts has prompted ongoing scientific research and the use of modern technological solutions. Until now, there have been no tests for the correct location of the geometric center of a double and outside slip turnout with the related geometric relationships. Therefore, the main objective of this research was to demonstrate the position of the geometric center of a double slip turnout and the geometric conditions of the curves of circular diverted tracks by measuring the horizontal versines and geometric irregularities of turnouts. The application of this surveying method, with reference to obtuse crossings and arising from geometric dependencies in the double and outside slip turnout, is defined and implemented (also known as a method for checking the correct location of the geometric center of a turnout-Surveying and Monitoring of the Geometric Center of a Double and Outside Slip Turnout (SMDOST)) via the Magnetic-Measuring Square (MMS) and electronic Total Station. This method also recommends measuring the horizontal versines of the diverted tracks. This paper presents the results of field measurements while using the SMDOST and MMS methods, which were applied to carry out an analysis and evaluation of the turnout geometry conditions, thereby presenting the irregularities that cause turnout deformations. The validity of the SMDOST method using MMS and Total Station was thus confirmed. The observations from the conducted research indicate that neglecting measurements of the geometry of the turnouts resulted in additional irregularities in their conditions.
