| 摘 要： | 建立了依据路堤填土期施工期和预压期观测资料计算路堤总瞬时沉降、总固结沉降、地基固结指数的基因反演方法,进而根据这三个反演参数计算最终沉降,并与实际值作比较,二者符合较好.此外,再依据预压期的沉降资料,分别利用三种不同的计算模型反演计算最终沉降,并与实测结果进行比较,进而对沉降计算模型的选取提出建议.

| Abstract: | Based on the monitoring data of settlement during construction and prepress period,this article has set up a genetic inverse analysis method to evaluate the entire immediate settlement,entire primary settlement and consolidation index.Then we can evaluate the final settlement according to the three indexes,then compare it with the monitoring data,and the result shows that both meet well.In addition,we use three different models to evaluate the final settlement by genetic inverse analysis method based on the monitoring data during the press period,and also compare it with the monitoring data in order to give some advice for choosing the proper computing model. |
