| 摘 要： | 公路、铁路等工程中通常利用实测沉降资料推算最终沉降，双曲线是最常用的一种沉降推算方法。工程实践表明，常规双曲线法即增量双曲线法推算沉降往往小于实际沉降，且需要较长时间的沉降资料。依托大量监测工程，在增量双曲线法的基础上，提出了全量双曲线法和TS双曲线法。工程实践表明，这两种新的双曲线法推算沉降与增量双曲线法推算沉降基本相同，可用于较短预压时间的沉降推算。

| Abstract: | 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. |
