摘　　要：在对广东科学中心工程地质情况进行勘察后,明确工程地质的特点及难点。经过对多种地基处理方法的综合比较分析后,决定选择动、静排水固结法处理地基。在现场试验的基础上,探讨了动力排水固结法的施工技术,包括施工工艺流程,排水系统施工及强夯施工具体过程,并验证了双向排水效果。通过工后检测,表明该技术处理饱和淤泥质砂土软弱地基具有良好效果。After the investigation of the engineering geological conditions in Guangdong Science Center,the construction characteristics and difficulties of the project are put forward.By the comparison among the foundation treatment methods,the static and dynamic drainage consolidation method to treat the soft soil foundation is chosen.On the basis of the field tests,the construction technology of dynamic consolidation by drainage including the construction process,the concrete process of the drainage system and dynamic compaction are discussed.Meanwhile,the two-direction drainage effect is proved.The data analysis of test and experiment results show that the method which is used to treat saturated silt sandy soil ground has good effect.
