利用轴对称荷载作用下的土工网格材料加固粘性土地基室内模型试验装置 ,研究了加筋参数 (加筋参数包括筋材的层数 N ,各筋材间的层间距 Z和筋材类型等 )对地基土承载力与抗变形能力的影响 ,以及长期荷载作用下地基土的变形规律 ,分析了压实度 K、土工网格间填土厚度等与加筋土变形之间的关系 With the help of geostrophic material under axisymmetrical load, the laboratory test of the clay soil foundation model was carried out. The parameters of reinforcement (such as the number of reinforcement N, the spacing Z of each reinforcement, the type of reinforcement, etc.) ) On the bearing capacity and anti-deformation capacity of foundation soil and the law of deformation of foundation soil under long-term load, and analyzed the relationship between compaction degree K, soil filling thickness of geotextile and deformation of reinforced soil
