摘要
以福州市渔平高速公路工程为依托,通过对赤表特大桥及东瀚互通主线右线桥高性能C50海工混凝土预制T梁施工过程中出现的外观质量病害进行原因分析和总结,进行工艺改进和优化混凝土配合比,最终在混凝土构件外观质量控制上取得了很好的成效。
This paper was based on Yuping highway project in Fuzhou city of Fujian province, through the analysis and summary of the apparent disease causes during the construction of Chibiao super large bridge and the precast T beam with marine engineering high performance C50 concrete of the right lane bridge in Donghan interoperability mainline. Then the construction technology was improved and the concrete mix proportion was optimized, which achieved good results in the apparent quality control of concrete.
