| With the fast development of high-speed railway construction, it’s difficult to avoid producing damages during the slab tracks’ service because of varies of complex factors, and the diseases will affect the track structure’s stability and durability, and reduce traffic safety and comfort. This article is about the high-speed railway’s subgrade nonuniform settlement, combined with the data collection and field experience, summarizing the causes of subgrade settlement, common regulation measures and control standards. At the same time, based on the Wuhan-Guangzhou Passenger Dedicated Line subgrade settlement, which is occurred on the K1711+365～+396 Line, the reasonable and feasible regulation measures and deformation monitoring methods are determined preliminarily, by analysing the settlement character and investigating the geological conditions.Firstly, based on the data collection and theoretical analysis, the preliminary causes of high-speed railway subgrade settlement deformation are determined, and the common subgrade prevention and regulation measures are also summarized according to the field experience.Secondly, by studying on the connection between the subgrade settlement standard and other factors, such as the maintenance technology and engineering construction cost, the subgrade settlement’s control standards, which are suitable for the high-speed railway in china, are summarized.Then, based on the Wuhan-Guangzhou Passenger Dedicated Line subgrade settlement, which is occurred on the K1711+365～+396 Line, the preliminary causes of subgrade nonuniform settlement are determined by combining the settlement character and geological conditions, and putting forward the reasonable and feasible regulation measures.Finally, according to the common deformation monitoring methods in the field, the preliminary deformation monitoring methods and requirements have been confirmed, which are used to carry on the deeply research of the effect of regulation measures. |
