| 摘 要： | 结合某轨道交通和下穿地道不均匀沉降实例，采用实测沉降监测数据分析了病害发生的原因及演变过程。分析结果表明:造成沉降差的主要原因是，由于其北侧的盲沟破坏导致了管涌，土体颗粒流失；其次是冻结融沉。

| Abstract: | Combined with the instance of uneven settlement between a rail system and underpass, the measured data of settlement monitoring was used to analyze the causes of diseases and the evolution process. The results show that the first reason of settlement difference is piping and loss of soil grains caused by the damage to blind ditch in the north side; and the second reason is freezing and thawing. |

| Keywords: | rail system settlement causes settlement monitoring piping freezing and thawing |
