摘要
结合具体工程,研究了滑动层摩擦系数对道床板纵向受力的影响,综合考虑温度力、制动力、断轨力和断板力作用下道床板的受力情况,得出滑动层摩擦系数为0.2左右时道床板受力比较合理的结论。
Combined with concrete project, it researches the sliding layer frictional parameters＇ effect to vertical force of road bed board. By considering the forcing situation under the effects of temperature force, breaking.force, track-breaking force and board-breaking force, it concludes that it is rational to have the road bed board force when the sliding layer frictional parameter is about 0.2.
