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 investigating the engineering geological conditions of the Guangdong Science Center, the characteristics and difficulties of the engineering geology are clarified. After a comprehensive comparison and analysis of a variety of ground treatment methods, decided to choose dynamic and static drainage consolidation method to treat the foundation. On the basis of field test, the construction technology of dynamic drainage consolidation method is discussed, including the construction process, drainage system construction and the process of dynamic compaction, and the bidirectional drainage effect is verified. Through post-test, it shows that the technology has good effect on the treatment of saturated silt sand and soil soft foundation.
