Study on the Evaluation Method of Subgrade Settlement Caused by Structure Layer of the High-Speed Railway

Abstract:

Based to the geometric and mechanical parameters of the typical high-speed railway, the settlement values on the foundation and the subgrade face with different structure layer load are obtained by the numerical calculation. According to these numerical results, the power functional relationship between Sst / S∞ and Pst /hγ is found, and a new evaluation method of the subgrade face settlement caused by the structure layer using the measure data is put forward. Through analyzing the settlement data of different conditions, the parameters of the formula are discussed, and some conclusions and suggestions are given. This new evaluation method will provide some reference for the design and the evaluation of the subgrade settlement caused by the structure layer of the high-speed railway.
