利用离心模型试验研究了下部加密、中间加密 ,全断面均匀加密三种布筋方式的加筋边坡的坡面侧向位移及位移场等变形性态。结果表明 ,中间加密布筋是加筋边坡经济合理的布筋方式。结合离心模型的试验成果 ,用断裂理论分析和解释了加筋在边坡土体剪切破坏过程中的阻裂机理 ,素土边坡和不同布筋方式加筋边坡的变形破坏机理 ,加筋边坡与素土边坡滑动面形状不同的机理 ,以及中间加密布筋是加筋边坡合理布筋方式的机理 ,得出了边坡中下部H/ 3 H/ 2范围内加密布筋是加筋边坡最经济合理的布筋方案的结论
Centrifugal model test was used to study the lateral deformation and displacement field of the reinforced slope with three kinds of reinforcement methods: lower part encryption, middle part encryption and full section uniform encryption. The results show that the middle cofferdam is an economical and reasonable method of reinforcing the cofferdam. Based on the experimental results of centrifugal model, the fracture mechanism of the reinforced soil is analyzed and explained by the fracture theory. The mechanism of deformation and failure during the shear failure process of the slope soil, the deformation and failure mechanism of the plain soil slope and the reinforced slope with different reinforcement methods, The mechanism of the different sliding surface shape of the slope between the slope and the plain soil and the reason that the middle cofferdam is the reasonable way of the reinforcement of the reinforced slope are concluded. The distribution of the cofferdam within H / 3 H / 2 in the middle and lower part of the slope It is the conclusion that reinforced slope is the most economical and reasonable reinforcement plan
