    摘要：由于地下粮仓长时间处在地下水的浸泡中，在选用聚丙烯塑料板作为地下粮仓的内衬防水层时，每块聚丙烯塑料板的焊接处是最关键的部位；不同焊接方式、焊接部位的抗水压强度是地下粮仓防水防潮的关键。针对不同的聚丙烯塑料板的焊缝形式，通过试验分析其各自的抗水压性能，为地下粮仓的防水防潮工艺提供更多的理论依据。

   Abstract：As the underground granary needs be soaked in groundwater for a long time，when the polypropylene plastic board was selected as the lining waterproof layer of underground granary，the welding area between the polypropylene plastic board becomes the most key parts; The compressive strength of different welding methods and welding parts is the key to achieve waterproof and moisture-proof properties of underground granary. According to the weld form of different polypropylene plastic boards，the respective hydraulic pressure resistance performances are analyzed through experiments，which provides more theoretical basis for the waterproof and moisture proof technology of underground granaries.
