摘　　要：我国陕南地区广泛分布膨胀土,因反复胀缩导致降雨情况下的PP织物袋筑坎破坏现象经常发生。设计了集防淤排渗功能于一体的PP织物袋,通过合理设计袋体孔径,整体提高排水性能,降低内部水压力,对加固稳定筑坎有深远意义。Expansive soil is widely distributed in the south of Shaanxi Province in China,the damage of PP fabric bag bank building often occurs under the condition of rainfall due to repeated expansion and contraction.In this paper,a PP fabric bag with the function of anti silting and drainage is designed,the pore diameter design of the bag body is reasonable,which can improve the drainage performance and reduce the internal water pressure,which is of far-reaching significance for strengthening and stabilizing the terrace bank.

关 键 词：膨胀土 PP织物袋 梯田筑坎 防淤排渗
