| 摘 要： | 分析了双曲线法、指数曲线法和三点法等预测超载预压情况下地基的工后沉降的局限性。反演导出沉降系数m,以反算的系数为沉降计算参数,同时考虑超载部分对工后沉降的影响,推导出能预测超载预压地基的工后沉降计算式,并针对沿海高速公路一段软土地基处理工程,较准确地预测了超载预压地基的工后沉降。

| Abstract: | Limitation of hyperbola method,exponential curve method and three-point method in prediction of post-construction settlement of surcharge preloading foundation is separately analyzed in this paper.Settlement coefficient m is derived through inversion,which is used as a parameter for settlement calculation.Meanwhile,considering the influence of surcharging section on post-construction settlement,the formula of post-construction settlement of surcharge preloading foundation is derived.According to the treatment project of a coastal expressway soft soil foundation,post-construction settlement of surcharge preloading foundation is predicted exactly. |
