本文对我国長钢軌线路设计中的兩个問题提出一些商榷意见:1)在我国气候条件下,温度应力式长轨线路除绝缘接头处外,似可采用長轨条与長轨条直接相联,而不必采用12.5米标准轨来联接的办法,并用实际计算来加以证明; 2)在定期放散应力式长轨线路中,如不采用调节器,宜采用二至三根普通長度的钢轨来联接,此外,并对下列情况--放散温度为33℃,轨条長度由400米至1200米--下的長轨线路提出接头处普通钢轨的布置方案。
In this paper, some suggestions are put forward on two issues in the design of long rail lines in China: 1) Under the climatic conditions of our country, except for the insulation joints of long-stress rail lines, long-rail and long-rail direct phase Joint, instead of using the 12.5-meter standard rail to connect the way, and to prove with the actual calculation; 2) In the regular release of stress-type long-track lines, without the use of regulators, should be used two to three ordinary length rail to connect In addition, an arrangement of common rail joints at the joints is proposed for the following cases - a long rail line with a radiating temperature of 33 ° C and a rail length of 400 to 1,200 m.
