The final settlement of such projects as highway,railway etc.is often predicted by way of the result of settlement monitoring.Hyperbolic method is adopted in settlement prediction most often.It is proven by many projects that the predicted settlement using normal hyperbolic method that is incremental hyperbolic method is often less than real final settlement.Result of long time settlement monitoring is needed by incremental hyperbolic method.Based on many projects of settlement monitoring and deep study of incremental hyperbolic method,total hyperbolic method and TS hyperbolic method are proposed.It is proven that the predicted settlement by the two new methods is almost same as that by incremental hyperbolic method and the two new methods can be used for projects whose time of preloading is short.
