对近10年来缩尺试验和足尺试验研究成果的总结和分析,结果表明:柔性基础下复合地基工作性状是柔性基础、垫层、复合地基及下卧层四者之间相互作用与应力应变耦合的结果;除桩土应力比外,桩土沉降差、土拱效应、中性点位置、土工格栅作用等也应得到重视;正交设计或均匀设计尚未广泛应用于试验;有必要将解析解、室内试验与原位测试、缩尺试验、数值模拟和足尺试验结合起来开展研究.

Based on summary and analysis of studies on reduced scale and full-scale experiments in recent ten years, it is concluded that(1) the behavior of the composite ground under the flexible foundation is the result of the interactions and stress-strain coupling among the flexible foundation,the cushion,the composite ground and the underlying stratum;(2) in addition to pile-soil stress ratio,the differential settlement between pile and soil,the soil arching effect,the position of the neutral point and the effect of reinforced geogrid should be paid more attention;(3) the orthogonal design or uniform design are not widely used in experiments;(4) it is necessary to comprehensively apply the analytical solution,the laboratory and in-situ tests,the reduced scale experiment,the numerical simulation and the full-scale experiment to the research.
