摘要: 本文通过挡土墙模型试验,测试到缓冲层的设置可降低裂土夯填造成对挡土墙过大的侧压力及裂土遇水膨胀造成对挡土墙的膨胀土压力。提出了设置缓冲层的合理厚度和配置。Abstract: The study has shown that buffering cushion installed in the model test of retaining wall can reduced la- teral pressures and swelling earth pressures produced by ramming and wetting of expansive soils(fissured clays The reasonable thickness of buffering cushion are recommended.
