给出了确定多层土工格栅加筋砂基极限承载力的小型室内模型试验结果。试验只使用一种类型的土工格栅和一种压实到一种相对密度的沙子。基础埋藏率在0~0.6之间变化。结果表明，对于给定的配筋比，极限承载力比随埋深的增加而增大。文中还给出了极限荷载下的承载比与极限沉降量(小于或等于地基宽度的5%)之间的关系。极限沉降时的承载比小于极限荷载时的承载比。
Results of small-scale laboratory model tests to determine the ultimate bearing capacity of a strip foundation supported by sand with multiple layers of geogrid reinforcement are presented. Tests were conducted with only one type of geogrid and a sand compacted to one relative density. The embedment ratio of the foundation was varied from zero to 0.6. It is found that, for the given reinforcement-depth ratio, the bearing capacity ratio with respect to ultimate load increases with embedment. The relationship between the bearing capacity ratio at ultimate load and at limited levels of settlement (less than or equal to 5% of foundation width) is also presented. The bearing capacity ratio at limited levels of settlement is smaller than the value at ultimate load.
