温州永兴北园软土地基采用改性真空预压处理方法,进行负压密封降水,在出水量明显减少,沉降量趋缓甚至无沉降的情况下,达到降低土层含水量;提高土体密实度、承载力;减少地基工后和差异沉降量的目的。本文依据软土地基恒载期的沉降观测数据,分别利用双曲线法和指数曲线法根据沉降观测数据进行沉降预测,通过对两种方法预测结果的分析比较,尽可能精确地推算地基最终沉降量。

By using the method of modified vacuum preloading treatment to vacuum sealing of precipitation, the soft soil ground in Wenzhou Yongxing North Park had achieved the goal of reducing the moisture content, improving the soil construction as well as soil bearing capacity, and reducing foundation work of differential settlement under the condition of safe-durable significantly reduced, which under the case of water discharge reducing and slowly or even without. Based on the soft soil foundation settlement of constant loading period observation data, it analyzed the resources of two methods of hyperbolic long---base method and exponential curve method that using in subsidence forecast according to settlement obserwaional data. The ground subsides finally the quantity has been calculation precisely.
