摘　　要：土工合成材料加筋土挡墙具有良好的力学性能和优越的经济性等优点,在国内外得到了越来越广泛的应用。分别研究了筋材刚度变化对返包式及砌块式两种挡土墙破坏形式的影响,通过验证后的建模数值模拟方法建立并分析了在不同土体条件下,加筋土挡墙内破裂面形式随着筋材刚度数值的变化规律。数值模拟结果表明,返包式挡墙一定范围内破裂面形式会随着加筋挡土墙筋材刚度的增大而贴近面板位置;砌块式挡墙一定范围内破裂面形式会随着加筋挡土墙筋材刚度的增大而远离面板。所得结论对相关工程具有较好的参考意义。Geosynthetic reinforced soil retaining wall has the advantages of good mechanical properties and superior economy,and has been more and more widely used at home and abroad.In this paper,the influence of the change of the reinforcement stiffness on the failure mode of the backpack retaining wall and the block retaining wall is studied respectively.Through the verified numerical simulation method,the variation law of the fracture surface form of the reinforced soil retaining wall with the stiffness value of the reinforcement under different soil conditions is established and analyzed.The numerical simulation results show that within a certain range,the fracture surface of the backpack retaining wall will move towards the panel with the increase of the reinforcement stiffness,while the fracture surface of the block retaining wall will move away from the panel with the increase of the reinforcement stiffness.The conclusions are of reference value for similar projects.
