TP水电站厂房安装间板梁修复及验证分析

Repair and verification analysis on plate girder at power house erection bay of TP hydropower station

厄瓜多尔TP水电站Alluriquín厂房安装间桥机实验吊钩脱落后,22 t重混凝土试块及副勾从4.8 m高处坠落在安装间744.00 m高程板梁结构上,对板梁结构造成了破坏,文中通过对板梁结构破坏程度的分析,提出了加固方案并通过计算进行验证。计算结果表明,加固结构满足工程安全要求。

After test hook falling off from the bridge crane in the erection bay of the Alluriquín power house of the TP hydropower station of the Republic of Ecuador,the 22 tons of concrete test block and the auxiliary hook hit the plate girder structure at 744.00 meter elevation from 4.8 meters high,and damaged the plate girder structure.The paper analyzes the damage degree of the plate girder structure,provides the reinforcement scheme and verified by calculation.The calculation results show that the reinforcement structure could meet the safety requirement of the project.
