The coupling between bridge and track adopts by beam unit, modulus of electricity of and yielding stress according to the broken line of the non-liner rail longitudinal resistance of displacement.

桥梁和轨道的联结采用非线性梁单元模拟，其材料弹性模量和屈服应力通过轨道纵向位移阻力与梁轨相对位移关系的双折线化确定；

As the bolt tension increase, the tension of rail web, stress of joint bar and stress of joint bolt would increase accordingly, but the displacement of rail would become smaller.

螺栓扭矩增大，接头区钢轨轨腰拉力、夹板应力、螺杆内应力都会增大，而钢轨位移会随着螺栓扭矩的增大而减小。

Network Rail said it wanted to stress the increased dangers of trespassing on the tracks.

On transport, rail patronage had increased which should be welcomed but it had to recognised that it put stress on a system that had suffered underinvestment over the years, said Mr Barber.
