摘　　要：通过膨胀力平衡法、路基动应力法、大气影响深度法对铁路工程中膨胀土产生的膨胀力的影响深度进行初步探讨,所得结论可供某些铁路膨胀土地段的设计借鉴参考。The expansibility equity and the active stress method of roadbed and the method of atmosphere incidence were used in this text to discuss expansibility incidence of expansive soil in railway project. The conclusion can be used for reference in some expansive soilrailwayroadbed.
