摘　　要：预制T梁是公路桥梁中最为普遍的一种上部结构形式,预制T梁制梁台座形式多样、止浆条材料种类繁多,梁场建设过程中往往因为台座设计不合理、止浆条材料选用不当等原因造成T梁成品存在较多质量缺陷,影响T梁的外观质量,后期需进行大量的缺陷修复工作。当出现T梁制梁台座设计不合理时,如何能快速对台座进行优化,不仅可以根治质量通病、消除质量隐患,并且能保证施工进度,节约施工成本。Prefabricated T-beam is the most common form of upper structure in highway bridges.Prefabricated T-beam pedestal has various forms and various grout stop materials.During the construction of beam yard,there are many quality defects in T-beam products due to unreasonable design of platform and improper selection of grout stop material,which affect the appearance quality of T-beam.A lot of defect repair work is required in the later stage.When unreasonable design of T-beam pedestal occurs,rapid optimization of pedestal can not only eliminate common quality problems and potential quality hazards,but also ensure construction progress and save construction costs.
