摘要
该文首先对固结度及沉降计算的常用方法进行简单的介绍,然后结合工程实例对双曲线法和三点法计算固结度和沉降预测做了对比分析。得出在真空预压处理软土地基时,运用双曲线法计算的固结度较三点法偏小,两种方法所得沉降预测曲线与实测曲线均吻合较好,三点法对工后沉降预测计算结果较小。因此,不同计算方法运用时应谨慎选择。
First the common method of calculating consolidation degree and settlement is briefly introduced , then the consolidation degree and settlement prediction calculated by hyperbola method and three-point method is comparatively analysis combined with project examples. The conclusions are obtained that consolidation de- gree calculated by hyperbola method is smaller than that by three-point method in vacuum preloading on treat- ing soft foundation, the settlement prediction curve by two methods and measured curve are well accorded, the settlement prediction results post construction calculated by three-point method is smaller. Choice should be carefully made when using different calculation methods.
