针对我国轨道加载试验车( Track Loading Vehicle，简称 TLV)加载测试时无法系统识别轨道不良状态的问题，在充分考虑 TLV移动加载为恒载的前提下，通过建立 TLV-高速板式无砟轨道/重载有砟轨道-路基动力学耦合模型，研究TLV移动加载经过轨道薄弱区段时轨道结构的动态特性，得出了砂浆离缝、道床板结、轨枕空吊等轨道结构不良状态的识别特征，可为我国利用 TLV 识别轨道病害、指导轨道养护维修提供理论依据。

According to the identification problem of the bad track structure state systematically in T LV loading test, this paper established the dynamic coupling model of T LV-Slab Ballastless T rack & Heavy-haul Ballast T rack-Subgrade under the consideration that T LV mobile loading is constant,studied the dynamic characteristics of track structure when the T LV mobile loading passes through the weak section along the track,proposed the identification features of the bad track structure state including mortar debonding,cement hardening and unsupported sleeper, which could provide a theory reference for T LV identification of the track diseases and track maintenance.
