在 4 0 0gt大型土工离心机上对 5 7～ 85m厚的高填方地基的差异沉降和最终沉降变形特性进行模拟。土工离心模型预测了该地基 72个月 (包括施工期 38个月 )时间～沉降过程发展曲线。试验结果表明 ,大型离心机模型试验是研究上述工程问题的有效手段 ,所得结论对合理确定地基处理方案、加固处理深度和加固程度以及回填所需方量具有参考价值和指导意义。
The differential settlement and the ultimate settlement of the high embankment of 5 7 ~ 85m thick were simulated on a 4 0 0 ge large-scale geocentrifuge. The geotechnical centrifuge model predicts the time-sedimentation process curve of the foundation for 72 months (including the 38-month construction period). The experimental results show that the large centrifuge model test is an effective method to study the above engineering problems. The conclusions obtained are of reference value and guiding significance for the reasonable determination of the foundation treatment scheme, the reinforcement depth and reinforcement, and the required square of the backfill.
