摘要
介绍了一种静动力联合排水固结法在深厚软基处理中的应用。为方便后续类似工程合理优化施工参数,在特定案例及参数基准值下,采用敏感性分析法对固结系数、固结时间、排水板间距、填土厚度及加载时间等影响固结度的参数进行了分析,得到了各参数对固结度的敏感性程度排序。
This paper introduces the application of a static and dynamic combined drainage consolidation method in the treatment of deep soft soil foundation to obtain the reasonable and optimized construction parameters for subse⁃quent similar projects.Under the specific case and specific parameter benchmark values,the sensitivity analysis method is used to analyze the parameters affecting the degree of consolidation,including the coefficient of consolida⁃tion,consolidation time,spacing between drainage plates,thickness of fill,and loading time of fill.The order of sen⁃sitivity of each parameter to the degree of consolidation is obtained.
