| 摘 要： | 温州浅滩工程软土地基深厚,通过采用塑料排水板、土土材料的复合加固法,并结合原位监测沉降稳定控制手段,解决了在高含水率深厚软基上建造堤坝的稳定控制问题。根据该工程的原位观测资料进行沉降预测分析,并提出一种基于传统指数曲线拟合法的软土地基分级施工情况下的沉降预测模型,该模型考虑了土体变形的非线性和固结性质随荷载的变化,将沉降拟合方程中的待定参数在2个不同荷载级中分别加以确定。

| Abstract: | The foundation of shoals in Wenzhou is soft and deep.The study solved the stability control issues of building seawalls on the deep soft foundation with high water content by combining(a composite method of using plastic drainage plates and soil materials)in-situ monitoring of settlement stability control method.After analyzing the observed data from in-situ monitoring and conducting a settlement prediction analysis,the paper brings forward a settlement prediction model for the classified construction on soft foundation,based on the conventional exponential curve fitting method.In the settlement equation,undetermined parameters are obtained in two different load levels considering the changes of nonlinear and consolidation nature of soil deformation as the load varies. |
