应答器是一种基于电磁耦合原理的点式传输设备，容易受到周围金属物的影响，因此安装在护轨旁边的应答器可能会受到护轨的干扰。到目前为止，尚未发现有文献报道护轨对应答器干扰的相关研究。本文通过FEKO软件对应答器进行建模仿真与实测验证，在应答器模型中加入护轨模型，仿真护轨对应答器的干扰，通过对护轨开槽尺寸进行优化，找出最合理的开槽尺寸。研究结果表明，护轨主要对应答器的串扰区造成干扰，在理想情况下护轨开槽尺寸不小于2 mm就能满足场强一致性的要求，并且开槽尺寸越大对应答器的干扰越小，但当开槽尺寸达到一定值时，通过增大开槽尺寸进一步减小护轨对应答器的干扰效果十分有限。

The balise is a point-type transmission device based on electromagnetic coupling and it is easy to be af-fected by surrounding metal objects . So the balise installed beside guardrails may be interfered by the guard-rails . Up to now , there has been no literature on interference from guardrail to balise . Therefore , the re-search in this respect has become essential . In this paper , the balise was modelled and simulated by Software FEKO and teats were made for verification . Then the model of guardrail was incorporated into the balise model to simulate the influence of guardrail on balise . The slotting length of guardrail was subjected to the process of optimization and the most rational slotting length of guardrail was found . The research results show as fol-lows :The guardrail mainly interferes in the crosstalk area of balise ;under ideal conditions , the slotting lengths not less than 2 mm can meet the requirement of an uniform field strength ;the longer the slotting length of guardrail , the smaller the interference in the balise , however , when the slotting length reaches a certain value , further lengthening the slotting length will impose very much limited effect on reducing the in-terference of guardrail in balise .
