为研究面板刚度、加筋长度和加筋刚度对加筋边坡拟静力地震稳定性的影响，对采用1.96 mm直径钢筋填充的加筋模型边坡进行了一系列的倾斜试验。试验中采用了具有不同抗弯刚度的全高铝板和具有不同抗拉刚度和界面摩擦角的加固材料，研究了它们对加固模型边坡极限倾角（或基于拟静力的临界地震系数）的影响。结果发现，在所研究的因素中，加固材料的界面摩擦角对墙体的拟静力抗震稳定性起着至关重要的作用。当钢筋界面摩擦角太小时，增加钢筋的面层刚度或抗拉刚度对极限抗倾承载力的影响很小。
A series of tilting tests on reinforced model slopes backfilled with regularly packed 1.96 mm-diameter steel rods were performed to investigate the relative importance of facing rigidity, reinforcement length and reinforcement stiffness for the pseudo-static seismic stability of reinforced slopes. Aluminium full-height panel with a wide range of bending rigidities and reinforcing materials with significantly different tensile stiffnesses and interface friction angles were used in the tests to investigate their effect on the ultimate tilting angles (or pseudo-static-based critical seismic coefficient) of the reinforced model slopes. It was found that, of the factors investigated, the interface friction angle of the reinforcing materials plays an essential role in the pseudo-static seismic stability of the walls. When the interface friction angle of the reinforcement was too low, increasing the facing rigidity or tensile stiffness of the reinforcement resulted in a negligible effect on the ultimate tilting ...
