| 摘 要： | 土体固结度是评价真空预压法加固土体效果的一个重要技术指标,而确定土体固结度的关键是土体最大沉降量的计算。本文结合工程实例,依据真空预压法施工前期土体沉降量的实测数据,利用双曲线拟合法进行拟合并预测土体最大沉降量及卸荷时的土体固结度,然后与常用的三点法预测结果进行对比,结果表明双曲线拟合法预测结果更加符合工程实际,且能保证工程的安全。

| Abstract: | The consolidation degree of soil is an important index of vacuum preloading effect and the crucial factor of determining consolidation degree is the calculation of the largest settlement.According to pre-settlement measured data in vacuum preloading engineering examples,this study predicts the maximum settlement and consolidation degree of soil at the end of project using hyperbolic fitting method.In comparison with the commonly-used three-point method,the results show that predictions of hyperbolic fitting method are more in line with engineering practice and can better ensure the safety of project. |
