| 摘 要： | 土体固结度是真空预压法加固土体效果的一个重要评价指标,地基最大沉降量的计算是确定土体固结度的关键。本文结合工程实例,分析了GM(1,1)灰色模型在真空预压沉降预测中的可行性,根据部分实测数据计算了地基最大沉降量及土体固结度,并与常用的三点法和双曲线法计算结果进行对比,结果表明GM(1,1)灰色模型的预测结果更符合工程实际。该研究对真空预压施工具有一定的指导意义。

| Abstract: | The consolidation degree of soil is an important index of vacuum preloading effect.The crucial factor of determining consolidation degree is the calculation of the maximum settlement.In combination with practical engineering examples,this paper analyzes the feasibility of GM(1,1) grey model in vacuum preloading engineering.With some measured data,the paper calculates the maximum settlement and consolidation degree,and then compares them with the calculation results of three-point method and hyperbolic method.The results show that GM(1,1) grey model is more practical in vacuum preloading engineering and it is therefore a good guide to the construction of vacuum preloading. |
