| 摘 要： | 结合某高速公路K98 028、K98 470两处路堤完工一年后才开始的断续的前期沉降变形监测成果，利用太沙基一维固结理论，在缺少固结参数而又无法对多层软土路基固结参数分别反演的情况下，通过对地基整体固结参数的反演及数理统计分析，来达到沉降变形和沉降时问预测的目的；并通过与不同方法最终沉降变形预测结果之对比，及沉降预测结果与监测成果之拟合对比，进一步论证了该方法的可行性。

| Abstract: | According to the discontinuous deformation monitoring of the prophase subsidence of K98+028 and K98+470 section of one speedway, which started after a year of the road bank completed, this paper, under the conditions of no consolidation parameters and being incapable of deducing the roadbed's consolidation parameters for each layer of multi-layer soft soil, utilizing Terzaghi's one-dimension consolidation theory and mathematical statistics, and through the deduction of whole consolidation parameters of groundsill, forecast the eventual subsidence deformation and time. At the same time, this paper, by means of the comparison among the calculation of final subsidence of different forecast methods, and the comparison between the forecast of the one-dimension consolidation method and motoring outcome, demonstrated the feasibility of the method ulteriorly. |
