摘　　要：随着高速公路建设的不断发展,对工程质量要求不断提高,特别是标准化建设对预制构件的质量要求越来越严。由于先张法预应力空心板聚苯乙烯内模施工工艺具有诸多优点及良好的社会效益,现已在国内先张法空心板预制施工中推广使用。该工法在河南省郑州机场至周口西华高速公路二期K30+700~K45+245得到成功应用。With the continuous development of expressway construction,the requirements for project quality are constantly improving,especially the requirements for the quality of prefabricated components in standardized construction are becoming more and more strict.Because the pre-tensioned prestressed hollow slab polystyrene internal mold construction process has many advantages and good social benefits,it is now widely used in the domestic pre-tensioned hollow slab precast construction.This construction method has been successfully applied in the second phase of K30+700~K45+245 of the He'nan Zhengzhou Airport to Zhoukou Xihua Expressway.
