We have studied the variational pattern of track geometrical form due to wheel/rail forces under the quasi-static for operating of rolling stock, and also have studied the actions on elastic displacements of constraint rail due to the thickness and stiffness of track pad.

由轮轨力所引起的线路几何形态的变化规律；在假定轮轨力不变的情况下，又研究了轨底垫层的厚度和刚度对于约束钢轨弹性位移所起的作用；为确定轮轴的弯曲变形对轮轨关系的影响，同时建立了轮对有限元模型，计算了轮对承载状态所发生的弹性变形。

The kinematically admissible velocity fields of the web, head and base of rail are determined, respectively, and the corresponding strain rate fields and the intensity of shear strain rate are also obtained. Then the plastic deformation power, the friction powers and the powers consumed on the velocity discontinuity surface are obtained.

然后分别给出了轨腰、轨头及轨底的运动学许可速度场以及相应的应变速度场和剪应变速度强度，并求出了相应变形区的塑性变形功率、速度间断面上消耗的功率以及由于摩擦产生的摩擦功率。

Based on the modeling and analysis of the CO_2 concentration in the tunnels and underground railway with shielding doors,points out that,in winter,with air exhausters on the top of the tracks and at the bottom of the platforms along the railway stations closed and piston air functioning only,the temperature condition can,but the fresh air can not,be satisfied in the tunnels during morning and evening rush hours.
