To have a further study of the new type soft subgrade reinforcing system of geocell reinforced gravel mattress and gravel pile composite foundation of its mechanism of load capacity and settlement development,three comparative model tests were designed and carried out under the direction of similarity theory and similarity criterions deduced through dimension analysis method.
为深入研究土工格室碎石垫层-碎石桩复合地基这一新型多元复合地基加固体系的承载力和沉降变形机理,应用量纲分析法推导了土工格室碎石垫层-碎石桩复合地基模型试验的相似准则,根据相似理论设计和完成了3组具有可比性的模型试验,获得大量荷载-沉降、桩土应力比和应力分布数据。
Corresponding calculation method and construction technique of gravel cushion for soft soil foundation treatment are briefly introduced.
结合具体的工程实践,对其工程地质和水文条件进行了分析,简述了碎石垫层处理软土地基的计算方法及具体的施工过程,实践证明,碎石垫层处理软土地基施工方便,工艺简单,质量易控制。
Several methods are used are to test the physicomechanical indices of the gravel cushion.
某厂对其碎石垫层地基使用多种方法现场测试其物理力学指标，并作室内模拟试验。
The optimum gradation of crushed stone cushion for a concrete face rockfill dam is d 20 =0 25～1 5 mm, with a maximum grain size of 40～100 mm and a relative density of D r >0 7, containing 30%～60% in weight fine particles whose diameter is less than 5 mm.
混凝土面板坝碎石垫层料的最佳级配是d2 0 =0 2 5～ 1 5mm ,粒径小于 5mm的颗粒含量应在 30 %～ 6 0 % ,最大粒径为 40～ 10 0mm ,相对密度Dr>0 7,这时 ,碎石垫层料的渗透系数满足 (10 -3 ～ 10 -4 )cm/s数量级 ,且具有较高的抗剪强度 。
