利用极限平衡理论分析土工格栅加固试件的抗压强度，推导出在拉力破坏和粘着破坏情形下相应的承载力和破裂角计算公式，并用试验数据进行分析验算。同时阐述了格栅层数和埋深对桩体强度的影响。
The limit equilibrium theory was used to analyze the compressive strength of the geogrid-reinforced specimens, and the corresponding formulae of the bearing capacity and fracture angle under the condition of tensile failure and adhesion failure were deduced, and the analysis and verification were performed with the test data. At the same time, the influence of the number of grid layers and the depth of burial on the strength of the piles is also described.
