| 摘 要： | 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。

| Abstract: | The simulation of the behavior for the differential an d final settlements of the high filling with the thickness of 57-85m is studied by using the 400gt geotechnical centrifuge. The prediction of the time-settleme nt curve for the foundation in 72 months(including construction period of 38 mon ths) is done with the centrifuge model. The testing results show that the large -scale centrifuge model test is effective to study the said issues. The results would have the guidable significance for the reasonable determination of ground treatment scheme, the depth of the treatment, the degree of soil improvement an d the quantity of filling. |
