以某高速铁路道岔区板式无砟轨道病害综合整治项目为背景，利用动态、静态检测技术全面评估了高铁道岔区板式无砟轨道的病害状况，主要有路基翻浆脱空、线路不平顺、钢轨动态竖向位移较大等问题。针对性提出综合治理措施，通过深层注浆来加固道岔区路基，对板底离缝进行注胶以修复、加固道岔板结构。结果表明：加固施工后，钢轨动态竖向位移显著减小，基床强度得以恢复，道岔动态检测叉心部位的左右高低、三角坑峰值均有所减小；剪切波速由250 m/s提升至350 m/s，电磁反射信号减弱。离缝注胶有效改善了轨道结构的接触状态；深层加固注浆后基床的均匀性、密实度提高，地基疏松、富水的情况得到有效改善。
Abstract：Taking a comprehensive treatment project for the slab ballastless diseases of track in a high speed railway turnout area as the background, the comprehensive evaluation of the disease status of the slab ballastless track in the high speed railway turnout area was carried out by using dynamic and static detection techniques, and the main problems include such as frost heave and void of roadbed, track irregularity, and large dynamic vertical displacement of steel rails. Targeted comprehensive management measures were proposed to reinforce the roadbed in the turnout area through deep grouting, and to repair and reinforce the turnout slab structure by injecting glue into the bottom joint of the slab. The results show that after reinforcement construction, the dynamic vertical displacement of the steel rail is significantly reduced, the strength of the foundation bed is restored, and the peak values of the left and right heights and triangular pits at the switch center of the dynamic detection of the turnout are reduced. The shear wave velocity is increased from 250 m/s to 350 m/s, and the electromagnetic reflection signal is weakened. The joint glue injection effectively improves the contact state of the track structure. After deep reinforcement grouting, the uniformity and compactness of the foundation bed are improved, and the loose and water rich conditions of the foundation are effectively improved.
