介绍了土工格室-碎石桩双向增强复合地基这一新型地基处理方法的处治技术及其特点,在分别对碎石桩复合地基和土工格室加筋体工作机理进行研究的基础上探讨了土工格室-碎石桩双向增强复合地基的加固机理,简要总结了土工格室-碎石桩双向增强复合地基试验研究、数值分析及双向增强复合地基的设计计算理论的研究现状。最后讨论了土工格室-碎石桩双向增强复合地基尚需进一步研究的问题。
The treatment technology and its character of the new foundation called the two- direction reinforced composite foundation formed by geocell reinforced mattress and gravel piles were introduced. Reinforced mechanism of two-direction reinforced composite foundation formed by geocell reinforced mattress and gravel piles on the basis of analysis of working mechanism of composite foundation formed by gravel piles and geocell reinforced mattress respectively was studied. The research progress on the experimental research, numerical analysis and the design theory of the two-direction reinforced composite foundation at home and abroad was summarized. Finally, some problems existed in two-direction reinforced composite foundation formed by geocell reinforced mattress and gravel piles in the future were discussed.
