計算鋼筋混凝土軌枕时,一般是考虑下列对綫路有影响的某些組合力:机車車輛的軸向荷载,因风作用而引起的附加力,由于直綫上車輛搖摆而产生的力,曲綫上的离心力和导向力。鋼筋混凝土軌枕的使用年限較长(30～50年),在計算中要考虑远景的軸向荷載25吨,但是,也曾研究了承受較小軸向荷載的結构方案。因风作用而引起的附加垂直力用下列方程式求算:△V_ω=±(H_ω·α_ω)/t, (1)式中:H_ω——最外輪軸問的車体側面上的风压合力; t——鋼軌轴綫間距离, α_ω——由軌頂踏面至合力作用点的距离。对于中欧条件来說,风压力可
Calculating reinforced concrete sleepers generally takes into account the following combinations of forces that have an effect on the line: the axial load on the rolling stock, the additional force due to the wind, the force due to the rolling motion of the vehicle on the curve, Centrifugal force and guiding force. Reinforced concrete sleepers have a long service life (30 to 50 years) and account for a long-term axial load of 25 tons in the calculation. However, structural solutions to minor axial loads have also been studied. The additional vertical force due to the action of the wind is calculated by the following equation: ΔV_ω = ± (H_ω · α_ω) / t, (1) where: H_ω - the wind pressure force on the vehicle body side of the outermost axle; t - Distance between rail axes, α_ω-- Distance from the rail tread to the resultant force point. For Central European conditions, wind pressure can be
