摘　　要：为了规避地下粮仓内衬钢板锈蚀对粮食造成的污染,推进内衬聚丙烯构件在地下粮仓的广泛应用,对内衬塑料板与混凝土的连接节点强度进行试验。探究栓钉直径和螺纹连接长度对节点强度的影响,得到不同栓钉直径和螺纹长度情况下构件破坏形态以及承载力之间的关系,进而为实际工程中的节点选取提供参考。in order to avoid the pollution caused by corrosion of lining steel plate in underground granary and promote the wide application of lined polypropylene members in underground granary,the strength of joint between lining plastic plate and concrete was tested.The influence of stud diameter and thread connection length on the joint strength is explored,and the relationship between the failure mode and bearing capacity of components under different stud diameter and thread length is obtained,which can provide reference for the selection of joint in practical engineering.
