摘要
针对强夯法加固饱和软粘土地基时超静孔压消散难和易出现"橡皮土"现象,提出强夯和排水固结二者结合的动力排水固结法,利用立体排水系统来加速夯后超静孔压的消散和软土固结,并结合某港口仓库软基加固工程进行了现场试验研究,对动力排水固结法的加固效应、加固效果及工艺特点等进行了分析和讨论。
In order to avoid the occurrence of 'rubbery soil'in saturated soft clay ground during the construction of dynamic consolidation method,the dynamic consolidation combined with drainage(DCD) using space drainage system to accelerate the dissipation of excess pore water pressure and the consolidation of soft soil and to improve the efficiency of dynamic consolidation has been proposed.The in\|situ test has been studied to verify the effectiveness of treating the saturated soft clay by the DCD on a large commercial warehouse ground in some port.The improvement influences and technology characteristics of the DCD improving the saturated soft clay ground have been analyzed and discussed.
