摘要： 根据实测沉降曲线推算路堤填筑后的最终沉降值，有多种方法可供选择。重点推介采用图解双曲线法和改进双曲线法推算最终沉降，并反求地基固结度。运用上述方法，以某工程为实例进行了推算，并与对数曲线法和指数曲线法推算结果比较，表明三者相差不大。

Abstract: There were many methods to calculate the final settlement of subgrade embankment according to the settlement monitoring result. The graphical hyperbolic method and improved hyperbolic method was introduced, then the consolidation degree of foundation was also calculated. The above discussed method was used in the engineering, its result was compared with the result calculated by the logarithmic method and the expotential curve method, there was no obvious difference among them by comparison.
