［摘要］为了研究采用尼龙网和直径为4-064mm的8号镀锌铁丝作为加强措施的改性生土墙体抗震性能，设计了两片采取上述加强措施的改性生土墙体试件和一片未采取上述加强措施的改性生土墙体试件，通过拟静力加载试验，对比分析了墙体试件的破坏特征、承载能力、滞回曲线及刚度退化等。研究结果表明，采用尼龙网和8号镀锌铁丝加强措施能够延迟墙体裂缝发展，增强墙体整体性能和改善墙体变形性能，使墙体的耗能能力提高，刚度退化延缓。因此，上述加强措施能有效改善生土建筑的抗震性能。

Abstract:In order to study the seismic behavior of  modified raw earth wall reinforced  with nylon web and galvanized iron wire No.8 with diameter of 4-064mm as strengthening measures, two  modified raw earth wall reinforced  specimens with the above strengthening measures and one modified raw earth wall specimen without the above measures were designed. The failure characteristics, load-carrying capacity, hysteresis loop and stiffness degradation of the specimens were compared and analyzed by quasi-static loading test. The test results indicate that the development of the cracks of  the wall   can be delayed, the whole performance of the wall can be strengthened and the deformation performance of the wall can be improved by using nylon web and galvanized iron wire No.8.  Moreover, the energy dissipation ability of the wall can be enhanced and the stiffness degradation of the wall can be delayed. Therefore, the above strengthening measures can effectively improve the seismic behavior of raw earth buildings.
