| 摘 要： | 基于地基固结理论,提出了考虑地基加固区下卧层修正的沉降资料反演固结系数的计算方法。结合通启高速公路沉降资料,反算出固结系数,相对室内固结试验成果高出1~2个数量级。并应用于计算路基沉降,与实验室测得的固结系数计算的沉降曲线进行对比和分析,得出了一些结论和建议。

| Abstract: | Based on the ground consolidation theory, the back-calculation method for consolidation coefficient is put forward in the paper taking into consideration of the field settlement amendment for the underlying stratum in the reinforced area. Based on the site settlement information of Tongqi expressway, the consolidation coefficient is back-calculated, it is 1 - 2 magnitude greater than that measured in the laboratory, and the result is used to work out the settlement of subgrade and compared with the laboratory test. Some suggestiom and conclusions are given. |
