Comparative Study of Gobi Soil Subgrade Settlement Forecasting Methods for Double Line 2 of Lanzhou-Xinjiang Railway

Abstract

the measured data of subgrade settlement on Double Line 2 of Lanzhou-Xinjiang Railway are used to analyze the suitability of the hyperbolic method, Hushino method and Asaoka method to Gobi soil subgrade settlement forecasting. The sensitivity of the methods to the data fluctuation and the influence of the forecasting error and the selection of forecasting start time on the forecasting effectiveness were studied to determine the appropriate forecasting methods and forecasting time.
