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。
In this paper, the common methods of the consolidation degree and settlement calculation are introduced briefly. Then the concordance and settlement prediction of the hyperbolic method and the three-point method are compared with engineering examples. The results show that the consolidation degree calculated by hyperbolic method is smaller than that of the three-point method when the soft foundation is treated by vacuum preloading, and the settlement prediction curves obtained by the two methods are in good agreement with the measured curves. The three-point method is suitable for post-construction settlement Prediction calculation results smaller. Therefore, different calculation methods should be carefully selected.
